Aplasia Cutis Myopia Syndrome

Aplasia cutis–myopia syndrome is an extremely rare genetic condition that links a birth defect of the skin with serious eye problems. Babies are born with a small area where the skin did not fully form (called aplasia cutis congenita). This area is usually on the scalp and looks like a thin scar or a patch without hair. The same person also has high myopia (very strong nearsightedness), often from early childhood. Many reported people also have congenital nystagmus (eyes that make quick, repeated movements), and tests can show cone-rod dysfunction in the retina (the light-sensing layer at the back of the eye). Because so few families have been reported, doctors consider this a “very rare” or “ultra-rare” disorder. Orpha+2Genetic Diseases Center+2

Aplasia cutis–myopia syndrome is an ultra-rare genetic disorder with two main parts. First, a baby is born with a small area of missing skin, most often on the scalp — this is called aplasia cutis congenita (ACC). Second, the person has very high short-sightedness (high myopia) along with eye movement problems (congenital nystagmus) and a problem with the light-sensing cells in the retina (cone–rod dysfunction), which can reduce vision from childhood. Only a handful of families have been reported worldwide. Because so few cases exist, doctors manage each person by combining what we know about ACC and what we know about high myopia/cone-rod disorders. Orpha+2Genetic Diseases Center+2

Scientists first described a brother and sister who both had scalp aplasia cutis, high myopia, congenital nystagmus, and cone-rod dysfunction. That report suggested autosomal recessive inheritance (both parents carriers). Some summaries list autosomal dominant inheritance. With so few cases, the true inheritance pattern is uncertain; both patterns may be possible or past summaries may differ. What is consistent is that the condition tends to run in families. PubMed+2Wiley Online Library+2

People with this syndrome can also show other eye changes, such as keratoconus (a thinner, cone-shaped cornea) or atrophy of the iris or retinal pigment epithelium. They may scar easily at the scalp lesion site. These findings were noted across the tiny number of published cases and catalog summaries. Wikipedia

Other names

• Aplasia cutis congenita, high myopia, and cone-rod dysfunction

• Aplasia cutis–myopia syndrome (ACM)

• Aplasia cutis with high myopia and congenital nystagmus (descriptive)

These names all refer to the same rare association of scalp skin aplasia with severe myopia and retinal cone-rod abnormalities. Medical dictionaries (Orphanet, GARD/NIH, MedGen, MONDO) use very similar phrasing. EMBL-EBI+4Orpha+4Genetic Diseases Center+4

Types

Because only a handful of families are published, there are no official subtypes. Clinicians instead talk about a phenotypic spectrum (range of features). The spectrum may vary by (1) where and how big the scalp aplasia cutis patch is; (2) how strong the myopia is; and (3) how severe the retinal cone-rod dysfunction and nystagmus are. Some case summaries also mention keratoconus or easy scarring as additional features. This “spectrum” language reflects the tiny evidence base rather than formal types. PubMed+1

Causes or contributors

Important note: For this ultra-rare syndrome, a single exact gene has not been established in the literature I could find. The list below explains plausible and evidence-informed contributors drawn from the published cases and from what is known about aplasia cutis congenita (ACC) and high myopia in general. I’m careful to say “possible” when evidence is indirect.

1. Genetic predisposition in families
   The first sibling report supports a hereditary basis. That paper proposed autosomal recessive inheritance. Later summaries list autosomal dominant in a catalog sense. With so few cases, both are discussed. PubMed+1

2. Developmental disruption of surface ectoderm (skin)
   ACC is a failure of normal skin development before birth, especially on the scalp. This general mechanism likely underlies the scalp lesion in this syndrome. NCBI

3. Vascular disruption to the scalp during fetal life
   ACC reviews describe reduced blood flow as one mechanism producing focal scalp defects; this is a widely accepted ACC pathway. NCBI+1

4. Amniotic band or mechanical factors
   Physical interference around the developing scalp can cause localized skin absence in classic ACC, which may also present within this syndrome. NCBI+1

5. Shared developmental pathways between skin and retina
   Although not proven for this syndrome, the co-occurrence of ectoderm-derived skin defects and retinal dysfunction suggests overlapping developmental programs that, when disrupted, affect both tissues. This is an inference from anatomy and case clustering. PubMed

6. Cone-rod dystrophy physiology
   Electroretinography in the index family showed cone-rod dysfunction, a primary retinal problem leading to reduced color and light sensitivity; this helps explain the severe myopia and nystagmus. PubMed

7. High axial length (eye grows too long)
   High myopia often reflects an elongated eyeball; in syndromic myopia this elongation can be secondary to underlying retinal or scleral biology. This is standard myopia physiology applied to the syndrome. Wikipedia

8. Connective tissue fragility at the scalp site
   Easy scarring at the lesion may reflect altered dermal collagen or healing responses, reported descriptively in cases. Wikipedia

9. Keratoconus association
   Keratoconus changes corneal shape and can worsen myopia/astigmatism in affected patients—mentioned in descriptive summaries of the syndrome. Wikipedia

10. Unknown locus (gene not yet identified)
    No definitive gene mapping is published for this very rare phenotype; that absence is itself an important “cause” category—“genetic, unknown gene.” Orpha+1

11. Environmental teratogens (for ACC generally)
    ACC literature notes drugs like methimazole and misoprostol, intrauterine infections, or trauma as possible contributors to isolated ACC. These are general ACC causes and not proven for this syndrome but are part of the differential thinking. Medscape+1

12. Chromosome anomalies in broader ACC contexts
    Some ACC occurs with chromosomal conditions (e.g., trisomy 13) or with 19q13.11 deletions, though those have their own syndromes; this helps clinicians rule in/out other diagnoses when ACC is seen. Medscape+1

13. Association with other ACC-linked syndromes (differentials)
    Conditions like Adams–Oliver or Knobloch can include scalp defects and ocular findings; they are look-alikes to separate from this specific syndrome. PMC

14. Family founder effect
    When a condition is seen in a single family, a rare private variant can be involved; this is a common pattern in ultra-rare inherited disorders. (General genetic principle applied to the 2-sibling report.) PubMed

15. Abnormal wound healing biology
    The thin scar or atrophic alopecia at the scalp site implies altered healing signaling, which may be part of the phenotype. (Clinical inference from case descriptions.) NCBI

16. Photoreceptor ciliary biology
    Cone-rod dysfunction often involves photoreceptor outer segment/ciliary pathways; not proven here, but consistent with ERG findings and known mechanisms in cone-rod dystrophies. (Background applied cautiously.) PubMed

17. Axial myopia progression in childhood
    Children with strong early myopia tend to progress; that progression is expected in this phenotype unless controlled by refractive care. (General myopia natural history, applied.) Wikipedia

18. Light sensitivity and nystagmus feedback loop
    Cone dysfunction can cause photophobia; nystagmus can worsen vision, which in turn increases visual strain. (Physiologic reasoning from cone-rod dysfunction.) PubMed

19. Scar alopecia from ACC site
    Loss of hair over the healed scalp patch is common in ACC and is part of this syndrome’s outward look. NCBI

20. Psychosocial impact as a secondary effect
    Visible scalp scarring and severe myopia can affect self-image, schooling, and quality of life; this is a recognized consequence in many congenital and visual disorders. (General pediatric dermatology/ophthalmology consideration.) NCBI+1

Common symptoms and signs

1. Scalp patch present at birth
   The hallmark is a small area where skin was absent in utero; by birth it often appears as a thin scar or membranous area, typically on the scalp vertex. NCBI

2. Atrophic alopecia over the patch
   Hair does not grow over the aplasia site, leaving a bald, scar-like spot. NCBI

3. High myopia (strong nearsightedness)
   Children need very strong minus lenses; distant objects are blurred without correction. This is part of the syndrome’s core triad. PubMed+1

4. Congenital nystagmus
   Involuntary eye movements start in infancy and can reduce visual clarity. PubMed

5. Reduced color vision and light sensitivity
   Cone dysfunction can cause color issues and photophobia. PubMed

6. Poor vision in bright light and sometimes at night
   Cone-rod dysfunction can reduce visual performance across lighting conditions. PubMed

7. Eye strain and headaches
   Heavy focusing demands from high myopia plus nystagmus can cause fatigue and headaches, especially during reading. (Clinical inference.) Wikipedia

8. Keratoconus (in some)
   A cone-shaped cornea can add irregular astigmatism and blur; mentioned in syndrome summaries. Wikipedia

9. Iris or RPE atrophy (reported)
   These structural retinal/iris changes can accompany cone-rod dysfunction and worsen visual function. Wikipedia

10. Easy scarring at scalp site
    The lesion area may scar easily and remain thin. Wikipedia

11. Photosensitivity
    Bright light bothers patients with cone problems; tints or filters may help. PubMed

12. Refractive amblyopia risk
    Very high uncorrected myopia in childhood can lead to “lazy eye” if not corrected early. (Ophthalmic principle applied.) Wikipedia

13. Psychological distress
    Visible scalp scar and severe visual impairment can affect confidence and social participation. (General pediatric impact.) NCBI

14. Infection risk in neonates (at the lesion)
    Open ACC lesions can be entry points for infection until healed; this is standard ACC care concern. NCBI

15. Family history of similar findings
    A history of the same triad in siblings supports a genetic syndrome. PubMed

Diagnostic tests

A) Physical examination

1. Full newborn/child skin exam
   The clinician inspects the scalp carefully. In ACC, a thin, scar-like patch or membranous area is typical. Size, location, and depth guide risk and follow-up. NCBI

2. Palpation of the scalp lesion
   Gently feeling the area helps assess thickness and whether there is any underlying bony depression or defect needing imaging. NCBI

3. Measurement and photography
   Measuring and photographing the lesion over time helps track healing and scarring. (Standard dermatology documentation.) NCBI

4. Hair and scar assessment
   Checking for atrophic alopecia and fragile scarring helps characterize the ACC site. NCBI

5. General dysmorphology review
   Because some ACCs are part of other syndromes, clinicians look for limb, skull, or vascular anomalies to rule out mimics (e.g., Adams–Oliver, Knobloch). PMC+1

B) “Manual” or bedside eye tests

6. Visual acuity testing
   Age-appropriate charts or fixation methods estimate clarity of vision and detect high myopia early. PubMed

7. Cycloplegic refraction
   Eye drops relax focusing so the true lens prescription is measured—key to quantifying severe myopia. Wikipedia

8. Ocular motility and nystagmus exam
   The doctor observes eye movements and nystagmus patterns, which relate to retinal function and vision stability. PubMed

9. Slit-lamp biomicroscopy
   This microscope exam checks cornea (for keratoconus signs), lens, and anterior eye structures. Wikipedia

10. Dilated fundus examination
    Looking at the retina and optic nerve helps identify pigmentary changes, macular issues, or myopic degenerative signs. PubMed

C) Laboratory & pathology-adjacent

11. Infection evaluation for open lesions (newborn period, if needed)
    If the ACC site is open or signs of infection are present, swabs or bloodwork may be done to guide antibiotics—standard ACC care, not specific to the syndrome. NCBI

12. Genetic counselling and family pedigree
    While no specific gene test is established for this exact syndrome, genetics teams review family patterns, consider broader gene panels (cone-rod dystrophy / syndromic myopia), and help with recurrence risk. PubMed

13. Targeted genetic testing (rule-outs/differentials)
    Depending on the overall picture, doctors may test for other conditions that combine scalp defects and eye disease to exclude them. PMC

D) Electrodiagnostic tests

14. Full-field electroretinography (ERG)
    ERG measures electrical responses of rods and cones. In the index family, ERG showed cone-rod dysfunction, supporting retinal involvement. PubMed

15. Pattern ERG (as available)
    This refines macular cone function assessment, useful when central vision is affected, in addition to full-field ERG. (Standard retinal testing principle.) PubMed

16. Visual evoked potentials (VEP)
    VEP measures brain responses to visual stimuli and can be useful when nystagmus or poor fixation makes acuity testing hard. (Common pediatric neuro-ophthalmic tool.) Wikipedia

17. Electro-oculography (EOG) (select centers)
    EOG evaluates the retinal pigment epithelium; some cone-rod conditions show abnormal EOG, providing another data point. (Background electrodiagnostic rationale.) PubMed

E) Imaging tests

18. Optical coherence tomography (OCT)
    OCT images retinal layers and the macula to document thinning or structural change expected with cone-rod dysfunction or high myopia. Wikipedia

19. Corneal topography/tomography
    Maps corneal shape to confirm or monitor keratoconus, which worsens vision in some reported patients. Wikipedia

20. Ocular biometry (axial length & keratometry)
    Measures eye length and corneal curvature; high myopia correlates with increased axial length. Helpful to track growth and guide lenses. Wikipedia

21. Cranial ultrasound (infants), CT or MRI (selected cases)
    Imaging is considered if the scalp defect is large, midline, or deep, to ensure bone and dura are intact—this is standard ACC safety practice. NCBI

22. High-resolution scalp ultrasound
    Bedside ultrasound can assess the soft tissues under the aplasia site without radiation in newborns. (ACC practice point.) NCBI

23. Serial clinical photography (dermatology & ophthalmology)
    Not “radiology,” but a visual record is a practical imaging surrogate to track lesion healing, scar stability, and ocular findings over time. NCBI

Non-pharmacological treatments (therapies & others)

Format: description (~150 words), then purpose and mechanism.

1. Gentle moist wound care for ACC (newborn period)
   Keeping the scalp lesion clean, moist, and protected helps skin grow from the edges. Parents usually apply sterile petrolatum or a similar barrier, change dressings as advised, and watch for redness, pus, or fever. Many small and even moderate scalp defects heal with this simple care over weeks to months. Evidence comes from neonatal dermatology reviews and case series where conservative care led to complete closure without surgery.
   Purpose: protect new skin, prevent infection, speed closure.
   Mechanism: moisture and barrier protection support keratinocyte migration and re-epithelialization while reducing trauma. AAP Publications+1

2. Non-adherent dressings
   Dressings that do not stick (e.g., silicone-coated mesh) reduce pain and damage during changes. They are cut to fit and replaced on a schedule set by the care team. This approach is standard in conservative ACC management.
   Purpose: painless protection and clean environment.
   Mechanism: creates a low-friction, moist microclimate to allow skin cell migration. PMC+1

3. Infection-prevention hygiene
   Caregivers wash hands before touches; the lesion is cleaned gently with sterile saline; monitor for fever or spreading redness. Early medical review is advised if infection is suspected.
   Purpose: lower neonatal sepsis risk.
   Mechanism: reduces bacterial load at a thin-skinned wound interface. AAP Publications

4. Sun and heat protection for the healing scalp
   Use shade and hats once dressings are no longer required, because new skin is thin and sensitive.
   Purpose: prevent burns and excess scarring or dyspigmentation.
   Mechanism: minimizes UV-induced inflammation and pigment changes in recently healed skin. AAP Publications

5. Ophthalmic refraction with glasses or contact lenses
   Early and frequent eye exams choose the right lens power for high myopia. Even with cone–rod dysfunction, clear optics can maximize remaining retinal function and support development.
   Purpose: sharper focus, better visual development, reduce eye strain.
   Mechanism: lenses shift the focal point onto the retina to improve image clarity. Genetic Diseases Center

6. Low-vision rehabilitation
   If cone–rod dysfunction limits visual acuity or color vision, low-vision services provide magnifiers, contrast enhancement, large-print materials, and training for school/work.
   Purpose: maximize independence and learning.
   Mechanism: compensatory optical and environmental adaptations increase effective visual input. Genetic Diseases Center

7. Lighting optimization and contrast-rich environments
   Brighter, well-diffused light, high-contrast print, and anti-glare tools help people with cone-rod issues function better.
   Purpose: reduce glare and enhance contrast sensitivity.
   Mechanism: improves signal-to-noise for impaired photoreceptor pathways. Genetic Diseases Center

8. Education on retinal-detachment warnings
   Teach warning signs (flashes, sudden floaters, curtain over vision) and the need for urgent care. High myopia raises lifetime retinal risks.
   Purpose: rapid response to vision-threatening emergencies.
   Mechanism: early surgical care is far more likely to preserve sight. PMC

9. Regular dilated retinal exams
   Periodic examinations catch peripheral retinal thinning, holes, or lattice early.
   Purpose: surveillance and timely prophylactic treatment if needed.
   Mechanism: early identification lowers detachment risk. PMC

10. Nystagmus strategies
    Head-posture adjustments (using a “null point”), larger print, and stable visual targets can reduce symptoms.
    Purpose: reduce oscillopsia and improve function.
    Mechanism: behavioral optimization around the patient’s null point and visual tasking. Genetic Diseases Center

11. Keratoconus monitoring and protective habits
    If keratoconus is present, avoid vigorous eye rubbing and schedule topography checks.
    Purpose: slow biomechanical progression.
    Mechanism: less mechanical trauma to a weakened cornea. Wikipedia

12. School accommodations
    Seat near the board, allow digital magnification, and use high-contrast materials and extra time during tests.
    Purpose: fair access to learning.
    Mechanism: environmental modifications offset acuity/contrast limits. Genetic Diseases Center

13. Developmental surveillance
    Vision issues can affect milestones; early referral to vision therapy and early-intervention services helps.
    Purpose: support motor/language development.
    Mechanism: structured sensory input and therapy compensate for vision loss. Genetic Diseases Center

14. Helmeting or padding (case-by-case) for large skull defects
    For wider ACC with bone involvement, teams sometimes use protective padding while healing or before surgery.
    Purpose: prevent trauma to thin bone/meninges.
    Mechanism: mechanical protection against impact. PMC

15. Care coordination across dermatology, ophthalmology, genetics
    A single plan aligns wound care, eye care, and family counseling.
    Purpose: reduce gaps in care.
    Mechanism: integrated follow-up for a multisystem rare disorder. Orpha+1

    Silicone gel/sheets and gentle massage after healing may improve scar quality.
    Purpose: better cosmetic outcome.
    Mechanism: hydration/pressure modulates collagen remodeling. Wiley Online Library

18. Vision-oriented assistive tech
    Screen readers, text-to-speech, and zoom features on phones/computers are practical daily aids.
    Purpose: maintain independence and productivity.
    Mechanism: software-based magnification and auditory substitution of visual tasks. Genetic Diseases Center

19. Safe physical activity and outdoor play
    General health, mood, and circadian rhythm benefit from outdoor time and exercise; use appropriate eye protection if ordered.
    Purpose: whole-body wellness.
    Mechanism: cardiometabolic and neurocognitive benefits support function despite visual limits. Genetic Diseases Center

20. Psychosocial support for child and family
    Coping with a rare condition is stressful; counseling and support groups (rare-disease communities) help.
    Purpose: mental health and adherence.
    Mechanism: lowers stress and improves engagement in care. Genetic Diseases Center

Dietary molecular supplements

There is no supplement proven to reverse cone–rod dysfunction here. Use food-first approaches and avoid megadoses without specialist advice.

1. Balanced protein & calorie intake
   Dose: daily diet with adequate calories/protein. Function: supports wound healing and general growth. Mechanism: provides amino acids and energy for collagen and keratinocyte repair. AAP Publications

2. Omega-3 fatty acids (e.g., fish twice weekly)
   Dose: dietary; discuss pediatric supplements if intake is low. Function: anti-inflammatory support; tear film quality for comfort. Mechanism: membrane and meibomian lipid effects; systemic inflammation modulation. Genetic Diseases Center

3. Lutein/zeaxanthin from foods (leafy greens, eggs)
   Dose: food sources preferred. Function: macular pigment support for contrast sensitivity in general eye health. Mechanism: antioxidant carotenoids concentrate in macula. Evidence in inherited cone–rod disease is limited. Genetic Diseases Center

4. Vitamin D sufficiency
   Dose: per national pediatric guidance. Function: bone/immune health. Mechanism: steroid hormone effects on calcium/immune pathways; indirect wound benefits when deficient. AAP Publications

5. Vitamin C from fruits/vegetables
   Dose: dietary RDA. Function: collagen cross-linking cofactor for wound healing. Mechanism: ascorbate-dependent hydroxylation of proline/lysine. AAP Publications

6. Zinc (food sources: legumes, meat, seeds)

Immunity-booster / regenerative / stem-cell drugs

Because this is an inherited oculocutaneous disorder, there are no approved “immunity booster,” “regenerative,” or “stem-cell drugs” proven to treat it. The safest approach is supportive care and standard treatment of complications. Experimental gene and cell therapies exist for specific retinal diseases (for example, RPE65-related disease), but not for this exact syndrome. Participation in research would only occur in formal clinical trials.
Bottom line: avoid unproven stem-cell clinics. Discuss research options with a tertiary ophthalmic genetics center. Genetic Diseases Center

(Given the safety concerns and lack of evidence, I’m not listing six separate “drugs” here; doing so would incorrectly imply they’re validated for this condition.)

Surgeries

1. Split-thickness skin graft for larger ACC
   Procedure: harvest a thin layer of healthy skin and graft onto the scalp defect once the wound bed is ready.
   Why: to speed closure, reduce infection/bleeding risk, and improve protection when the defect is large. Wiley Online Library

2. Local rotational flap
   Procedure: nearby scalp skin is rotated/advanced to cover the defect.
   Why: provides durable coverage with similar tissue when primary closure is impossible. Wiley Online Library

3. Cranioplasty (selected cases with bone defect)
   Procedure: surgical reconstruction of skull bone if large bony aplasia or risk to brain.
   Why: mechanical protection and cosmesis once child is an appropriate age. PMC

4. Corneal cross-linking (if keratoconus co-exists)
   Procedure: riboflavin drops and UV light stiffen corneal collagen.
   Why: to slow/stop keratoconus progression and preserve vision. Wikipedia

5. Retinal detachment repair (scleral buckle or vitrectomy)
   Procedure: seal retinal breaks and reattach retina using buckle and/or vitrectomy with laser and gas/oil.
   Why: high myopia raises detachment risk; timely surgery saves sight. PMC

What to eat and what to avoid

What to eat: regular meals with good protein (fish, eggs, legumes), colorful vegetables and fruits (vitamin C, carotenoids), whole grains, iron-rich foods, and omega-3 sources (fish, nuts/seeds if age-appropriate). These support growth, wound repair, and general eye health. Maintain normal vitamin D by diet plus safe sun per pediatric advice. Hydrate well. AAP Publications+1

What to avoid: megadose supplements (especially vitamin A) without medical advice; unregulated “stem-cell” or “vision cure” products; eye rubbing; excessive sun/UV on newly healed scalp; and in pregnancy, avoid antithyroid drugs linked with ACC (switch only under doctor guidance).

Frequently asked questions (FAQs)

1) Is there a single gene known for this syndrome?
Not yet. Reports are so few that a specific gene hasn’t been confirmed; inheritance has looked recessive in one family and dominant in summaries. Exome/genome testing may be discussed individually. PubMed+1

2) Will the scalp skin grow back?
Small to moderate ACC areas often close with careful moist wound care over weeks–months. Larger defects may need grafts or flaps. Wiley Online Library

3) Does high myopia always get worse?
Progression varies. High myopia increases lifetime retinal risks, so regular dilated exams are vital even if glasses remain stable. PMC

4) Can low-dose atropine eye drops help?
They can slow school-age myopia progression, but benefit in congenital high myopia with cone–rod dysfunction is uncertain; decision is specialist-specific. Genetic Diseases Center

5) What is cone–rod dysfunction and how does it affect life?
Cones (daylight/color) and rods (dim-light/peripheral) work sub-optimally, causing reduced acuity/contrast and possible night issues. Low-vision rehab and assistive tech help. Genetic Diseases Center

6) Is nystagmus treatable?
There is no simple cure for congenital nystagmus, but positioning strategies, optical aids, and support can improve daily function. Genetic Diseases Center

7) Are there warning signs of a retinal emergency?
Yes: flashes, new floaters, or a dark curtain. Seek urgent eye care. PMC

8) Can my child attend regular school?
Yes. With accommodations (seating, large print, magnification), most children can participate fully. Genetic Diseases Center

9) Are contact lenses safe in children?
When fitted and supervised by pediatric eye care teams, contacts can be safe and provide better optics in high myopia for some children. Genetic Diseases Center

10) Will glasses or surgery fix cone–rod dysfunction?
Glasses correct focus but not photoreceptor function. There is no approved surgery for cone–rod dysfunction; treatment focuses on maximizing usable vision and managing complications. Genetic Diseases Center

11) Could keratoconus happen here?
Some reports note keratoconus; if present, cross-linking may slow it. Avoid rubbing. Wikipedia

12) Is silver sulfadiazine recommended for the scalp?
Generally no in neonates unless a specialist advises it; many cases heal with petrolatum/barrier care and selective antibiotics. Wiley Online Library+1

13) What about gene or stem-cell therapy?
There is no approved gene or cell therapy for this exact syndrome. Consider research only through reputable trials. Genetic Diseases Center

14) Can medicines in pregnancy cause ACC?
Case reports link early-pregnancy methimazole/carbimazole with ACC; treatment choices for maternal thyroid disease should be planned with obstetrics/endocrinology. Oxford Academic

15) Where can we learn more about this rare disorder?
Orphanet, MedlinePlus/GARD, and MedGen keep concise rare-disease summaries and links. Orpha+2Genetic Diseases Center+2
