Hypertelorism–hypospadias–polysyndactyly syndrome is a very rare condition present from birth. It affects how the face, hands/feet, and genitals form in the baby. “Hypertelorism” means the eyes are wider apart than normal. “Hypospadias” means the urine opening in boys is on the underside of the penis. “Polysyndactyly” means there are extra fingers or toes, and some fingers or toes may be joined (webbed). Doctors think this syndrome belongs to a family of disorders called acro-fronto-facio-nasal dysostosis, which mainly affects the front of the skull/face and the limbs. Only a small number of children have been described in medical journals. Because it is so rare, doctors often use careful clinical examination and a set of tests to make the diagnosis and to rule out similar conditions. Some families reported in the literature had parents who were related (first cousins), so an autosomal recessive inheritance has been suspected in this particular pattern that includes genitourinary anomalies. Global GenesPubMed

This syndrome is a group of differences present from birth. Three main features are seen. The first is hypertelorism, which means the eyes are set wider apart than usual. The second is hypospadias, which means the opening of the urethra is on the underside of the penis, not at the tip. The third is polysyndactyly, which means there may be extra fingers or toes (polydactyly) and some fingers or toes may be joined together by skin or tissue (syndactyly).

Most cases are genetic in origin, meaning a difference in DNA that affects how the embryo develops. Several gene pathways can be involved. Examples include genes that guide midline development of the face and genitals (such as MID1 in Opitz G/BBB), and genes that guide limb patterning (such as GLI3 in Greig cephalopolysyndactyly). Sometimes a microdeletion or duplication on a chromosome is present. In many children, testing does not find a cause even with modern sequencing. That does not change care. Treatment is based on needs, not only on the name.

What it means in everyday words

• The face grows differently, especially the area between the eyes and the nose.

• The hands and feet can have extra or joined digits.

• In boys, the urinary opening may be in an unusual place; the scrotum can sometimes be split (bifid) or shawl-shaped.

• Some children can also have eye problems (for example, droopy eyelids, bulging eyes, infant glaucoma) and, rarely, a small herniation of brain tissue through the skull bone (frontal encephalocele). These features have been described in published case reports of this syndrome or its very close variants within acro-fronto-facio-nasal dysostosis. PubMed

Other names

Doctors and databases have used several names that point to the same or very closely overlapping pattern:

• Acrofrontofacionasal dysostosis type 2

• Acrofrontofacionasal syndrome type 2

• Naguib–Richieri-Costa syndrome (after authors who described families with this pattern)

All of these terms tie back to the same very rare pattern combining wide-spaced eyes, genital differences (like hypospadias), and extra or webbed digits. Global Genes

Type

Because so few patients exist worldwide, there is no single official “subtype list.” In clinics, doctors often group patients by how the features appear and by what the tests show. These practical “types” help with care planning:

1. Classic triad type: clear presence of the three key features—hypertelorism, hypospadias in boys, and polysyndactyly/syndactyly—plus a characteristic frontonasal look (broad nasal bridge, midline nasal groove). PubMed

2. Cranio-ocular enriched type: the classic triad plus stronger eye/skull findings (ptosis, proptosis, eyelid coloboma, congenital glaucoma, sometimes frontal encephalocele). PubMed

3. Genitourinary-enriched type: the classic triad plus more pronounced genital differences (bifid or shawl scrotum, cleft glans) or urinary tract anomalies. PubMed

4. Partial/attenuated type: two of the three key features are present (for example, hypertelorism and polysyndactyly) with subtle genital findings. This still requires careful exclusion of look-alike syndromes. (Clinical inference based on published spectra.) PubMed

5. Overlap/differential diagnosis type: findings suggest HHPS, but genetic testing or extra features point more strongly to a different, overlapping syndrome (for example, Opitz G/BBB). This grouping is used during evaluation so children are not mislabeled. NCBIGARD Information Center

Note: Some reports favor the term “autosomal recessive acro-fronto-facio-nasal dysostosis with genitourinary anomalies,” which is considered the same or a very close entity to HHPS. PubMed+1

Causes

Because the syndrome is extremely rare, the exact gene is not yet confirmed for this specific triad subtype. However, medical authors have noted autosomal recessive inheritance in multiple families, which means both parents silently carry one copy of a non-working gene, and the child receives both copies. Below are 20 causes or mechanisms, grouped and explained in plain English, reflecting what is known or reasonably inferred from closely related frontonasal/limb-patterning biology. Each item says what it is and why it could lead to the HHPS pattern:

1. Autosomal recessive single-gene variant (unknown gene yet): Reports with consanguineous parents and sibling recurrences suggest a recessive gene change drives the pattern. PubMed+1

2. Disrupted early facial midline development: The frontonasal prominence forms the bridge of the nose and space between the eyes. If its growth signals are off, eyes can be wide apart (hypertelorism) and a midline nasal groove can appear. (General mechanism from frontonasal dysplasia literature.) PubMed

3. Abnormal limb bud patterning: The same embryo signals that shape the face also help pattern fingers and toes. Small changes can cause extra digits and webbing. (Frontonasal/limb developmental coupling discussed in reviews.) PubMed

4. Disturbed tissue fusion in hands/feet: The webs between fingers and toes normally thin out before birth. If this programmed thinning is incomplete, syndactyly remains. (General limb development principle.) PubMed

5. Genitourinary tube positioning error (hypospadias): Forming the urinary channel in males requires exact midline closure and hormone-sensitive steps; small developmental shifts can move the opening downward. (Well-established hypospadias mechanism; GU anomalies were frequent in related “hypertelorism-hypospadias” cohorts.) PubMed

6. Abnormal skull bone seam (suture) growth: The midline skull and facial bones must grow in harmony; if growth is uneven, the orbits can move further apart. (General craniofacial growth mechanism.) PubMed

7. Eyelid formation differences (ptosis/coloboma): Early eyelid development is delicate; if edges fail to form or fuse normally, lids can be droopy or have a notch. (Mechanism consistent with the ocular features reported.) PubMed

8. Anterior skull base gap (encephalocele): A small opening in the front skull bone can allow tissue to bulge forward; this is rare but reported in HHPS-like cases. PubMed

9. Embryo signaling imbalance in frontonasal pathways: Pathways like SHH/FGF/BMP/GLI guide midline and limb patterning. Even if the exact HHPS gene is unknown, subtle changes in these routes can create the observed combination. (Biological inference supported by frontonasal dysplasia reviews.) PubMed

10. Modifier genes: Children with the same main variant may look different because other genes change the strength of signals during face/limb formation. (General genetic principle for variable expressivity.) PubMed

11. Noncoding DNA changes (gene switches): Variants in promoters/enhancers that turn genes on/off in the face or limb can mimic disease even when coding regions look normal. (General developmental genetics concept.) PubMed

12. Epigenetic influences: Chemical marks on DNA can change how development genes work without changing the DNA letters. In rare syndromes, epigenetics can modify severity. (General principle.) PubMed

13. Somatic mosaicism (rare): A change that happens after conception in some cells can cause patchy or asymmetric features. (General concept in dysostoses.) PubMed

14. Vascular/space constraints in early embryo: Subtle early blood supply or space issues can influence midline and limb patterning and contribute to webbing or extra digits. (General hypothesis used in craniofacial anomalies.) PubMed

15. Maternal–placental factors: These usually do not cause specific patterns, but severe nutrient or environmental issues at key weeks might worsen an existing genetic tendency. (Cautious, general statement.) PubMed

16. Hormonal micro-environment in male genital development: Even with a structural gene issue, small hormone signal differences can change the final position of the urethral opening. (Hypospadias biology.) PubMed

17. Undetected microdeletions/duplications: Standard chromosomes can be “normal” while tiny DNA losses/gains (CNVs) exist; advanced tests may be needed to detect them. (General cytogenetics concept.) PubMed

18. Gene–environment interaction: A mild gene variant may cause disease only when combined with an environmental stressor during a sensitive developmental window. (General developmental concept.) PubMed

19. Pathway overlap with look-alike syndromes: Disorders like Opitz G/BBB (MID1 or 22q11.2/SPECC1L) share some midline features but are genetically distinct; careful testing helps separate them. (Important for differential diagnosis.) NCBIGARD Information Center

20. Currently unknown factors: Because only a handful of cases exist, unknown genes or combinations may be involved; future sequencing studies may solve the cause. (State of the science.) PubMed+1

Symptoms and signs

Not every child has every feature. The list below gathers features reported in HHPS or in the closely overlapping “autosomal recessive acro-fronto-facio-nasal dysostosis with genitourinary anomalies.” Each item includes a short explanation of how it looks or feels:

1. Hypertelorism (wide-spaced eyes): The inner corners of the eyes sit further apart than usual, giving a broad nasal bridge appearance. PubMed

2. Broad nasal bridge with midline groove or dimples: A shallow groove along the top of the nose or small pits near the bridge is sometimes seen. PubMed

3. Proptosis or prominent eyes: The eyes may look more “bulging.” This can be structural and needs eye examination. PubMed

4. Ptosis (droopy eyelids): Upper lids can droop and partially cover the pupils, possibly affecting vision. PubMed

5. Polysyndactyly: Extra fingers or toes; some may be fused or webbed, most often affecting the hands and/or feet. PubMed

6. Broad thumbs or big toes: The first digits can be wider than usual. PubMed

7. Syndactyly between central fingers (for example, 3rd and 4th): Webbed soft tissue may join the digits. PubMed

8. Hypospadias in boys: The urethral opening lies on the underside of the penis; severity ranges from mild to severe. PubMed

9. Bifid or shawl scrotum (in some boys): The scrotum can be split or wrap around the penis. PubMed

10. Cleft glans (in severe hypospadias): The tip of the penis can be cleft, requiring urologic repair. PubMed

11. Frontal encephalocele (rare): A small herniation at the front of the skull; may be associated with skull base defect. PubMed

12. Congenital glaucoma (rare): High eye pressure from birth; needs urgent eye care to protect vision. PubMed

13. Eyelid coloboma (rare): A notch or gap in the eyelid tissue. PubMed

14. Facial shape differences (wide forehead, microbrachycephaly in some): Head can be a bit small and broad, with a wide forehead. PubMed

15. Possible urinary tract differences: Because genitourinary anomalies cluster with hypospadias in related cohorts, kidneys and ureters may need screening even if no symptoms are obvious. PubMed

Diagnostic tests

Doctors diagnose HHPS mainly by clinical examination and by excluding similar syndromes. Because genetic knowledge is still evolving for this exact triad-pattern, testing focuses on describing all involved systems and ruling out look-alike conditions.

A) Physical examination

1. Detailed dysmorphology exam: Head and face measurements (inter-canthal distance, interpupillary distance, nasal bridge width), eyelid position, and nose groove are checked and compared with age norms. This confirms hypertelorism and frontonasal differences. PubMed

2. Hand and foot inspection: Counting digits, looking for webbing or broad thumbs/halluces, and noting symmetry helps define polysyndactyly and syndactyly pattern. PubMed

3. Genital/inguinal exam in boys: Position of urethral opening, scrotal shape (shawl/bifid), and testicle descent (cryptorchidism) are documented; severity guides surgical planning. (Hypospadias is a core feature in related midline syndromes.) PubMed

4. Eye exam at bedside: Screening for ptosis, proptosis, corneal clarity, and basic light response; suspicious findings trigger full ophthalmology tests. PubMed

5. Neurologic observation: Head size/shape, fontanel size, and any mass or sac over the front skull raise concern for encephalocele, which then prompts imaging. PubMed

B) Manual or bedside measurements

6. Anthropometry: Standardized tape measurements for craniofacial distances confirm hypertelorism and support diagnosis. (Clinical standard.) PubMed

7. Penile length and curvature assessment: Gentle measurement helps document associated chordee in hypospadias and plan repair. (Urology standard within hypospadias care.) PubMed

8. Hand/foot range-of-motion checks: Determines function across extra or webbed digits and guides timing of hand surgery. (Orthopedic practice.) PubMed

9. Vision screening: Fix-and-follow testing in infants, later visual acuity, and lid function checks to see if ptosis affects vision development. PubMed

C) Laboratory and pathological tests

10. Chromosomal microarray (CMA): Finds tiny deletions/duplications that standard karyotype can miss; useful to rule out other syndromes with overlapping features. (General genetics approach; earlier HHPS cases had normal routine chromosomes.) PubMed

11. Targeted gene panels / exome sequencing: Panels for frontonasal dysplasia/limb patterning/craniofacial genes (and exome when needed) help exclude Opitz G/BBB (MID1) and 22q11.2/SPECC1L forms that can mimic parts of the picture. A negative result does not rule out HHPS, but narrows the differential. NCBIGARD Information Center

12. Endocrine evaluation if indicated: In severe genital differences, hormone tests (testosterone, LH/FSH) may guide hypospadias care; usually normal but important if ambiguity exists. (Hypospadias care principle.) PubMed

13. Basic metabolic and infection screens: Routine newborn labs are usually normal, but they help exclude other causes of poor growth or illness that might complicate surgery. (Clinical practice.) PubMed

14. Pathology of excised tissue (surgical): If digits are removed or webs released, tissue may be sent to pathology; this confirms the type of tissue and rules out rare masses. (Surgical standard.) PubMed

D) Electrodiagnostic tests

15. Visual evoked potentials (VEP) (if eye pathway concerns): Measures the brain’s response to visual signals—useful if congenital glaucoma, ptosis, or proptosis has limited visual development. PubMed

16. Electroretinography (ERG) (selected cases): Checks retina function when congenital eye disease is suspected along with the craniofacial features. (Ophthalmic standard in complex congenital cases.) PubMed

17. Brainstem auditory evoked responses (BAER) (if hearing concerns): Some craniofacial syndromes have associated ear/hearing issues; testing ensures early support if needed. (General craniofacial practice.) PubMed

E) Imaging tests

18. Brain and skull MRI: Looks for frontal encephalocele or other midline brain differences; also checks the corpus callosum and cortical patterning. Reported HHPS-like cases used MRI to define encephalocele and cortical changes. PubMed

19. Ophthalmic imaging: Corneal diameter, ultrasound biomicroscopy (when needed), and optic nerve evaluation assist in congenital glaucoma assessment and surgical planning. PubMed

20. Hand and foot X-rays: Map extra digits, bone structure, and joint positions before surgery. (Standard orthopedic imaging.) PubMed

21. Renal and urinary tract ultrasound: Screens for kidney/ureter anomalies that sometimes accompany hypospadias-centered syndromes. PubMed

22. Pelvic/scrotal ultrasound (boys): Checks for undescended testes and scrotal structure when shawl/bifid scrotum is present. PubMed

23. Echocardiogram (when clinically indicated): Some midline syndromes can carry heart differences; screening is reasonable if exam suggests it or as part of comprehensive evaluation. (General craniofacial syndrome work-up.) GARD Information Center

24. 3D facial photography or CT (selected): Helps quantify hypertelorism and plan craniofacial surgery if ever needed; usually not required unless severe. (Craniofacial planning practice.) PubMed

Regenerative / stem cell” drugs — safety note

There are no approved stem cell or regenerative drugs for this syndrome. Unregulated “stem cell” clinics are risky and should be avoided. The safest, evidence-based ways to protect health are:

1. Routine childhood vaccines — Doses per national schedule; mechanism: train adaptive immunity; benefits: prevents serious infections that could complicate surgeries.

2. Seasonal influenza vaccine — Annual; reduces flu-related complications and hospital days.

3. Vitamin D (as above) — Immunomodulatory support with bone benefits.

4. Zinc (as above) — Supports innate and adaptive immune function.

5. Good sleep and nutrition — Not a drug, but more effective and safer than unproven products.

6. Clinical trial therapies only — Any gene/stem-cell approach must occur in regulated trials with protocol-specific dosing. Do not use outside trials.

Surgeries

1. Hypospadias repair (urethroplasty)
   Procedure: Repositions the urethral opening to the tip of the penis and straightens curvature if present. Often done in infancy or early childhood in one or two stages.
   Why: Improves urinary stream, reduces spraying, supports sexual function in adulthood, and improves appearance.

2. Syndactyly release (hand/foot separation)
   Procedure: Z-plasty or skin-graft techniques to separate joined digits; staged if multiple webs are involved.
   Why: Restores finger or toe independence for grasp, pinch, balance, and shoe comfort.

3. Polydactyly correction (extra digit removal/reconstruction)
   Procedure: Excision of nonfunctional extra digit with ligament/tendon reconstruction when needed.
   Why: Improves hand/foot function, prevents shoe pressure, and eases fine-motor tasks.

4. Orchiopexy (if undescended testis exists)
   Procedure: Mobilizes and secures testis in the scrotum.
   Why: Protects fertility potential, improves exam access for cancer surveillance, and reduces torsion risk.

5. Craniofacial/orbital surgery for severe hypertelorism (select cases)
   Procedure: Team-based osteotomies to move orbits closer in older children when functional or psychosocial needs are significant.
   Why: Improves binocular field alignment and facial balance; reserved for severe cases in experienced centers.

Prevention and health-protection steps

1. Attend regular pediatric and surgical follow-ups to monitor growth and function.

2. Keep vaccinations up to date to reduce infection risks around surgeries.

3. Practice hand hygiene and wound care after procedures.

4. Maintain hydration and fiber to prevent constipation, which can worsen urinary symptoms.

5. Use sun protection on healing scars to avoid discoloration.

6. Follow urology guidance on catheter and dressing care exactly.

7. Encourage daily active play to build strength and coordination safely.

8. Create a school care plan so teachers know restrictions and supports.

9. Ensure sleep routines to support immunity and mood.

10. For future pregnancies in the family, seek genetic counseling and periconception folic acid.

When to see doctors

Seek medical care urgently if there is fever, spreading redness, foul wound drainage, severe pain not controlled by the plan, inability to pass urine, vomiting with dehydration, sudden scrotal pain/swelling, or high-pitched crying in infants. Schedule prompt visits for catheter issues, new lumps or hernias, recurrent UTIs, persistent constipation, poor weight gain, feeding trouble, or concerns about learning, speech, or behavior. Before sports or new therapies, check with the care team to confirm safety.

What to eat and what to avoid

What to eat:

1. Protein-rich foods (eggs, fish, poultry, dairy/legumes) to support healing.

2. Colorful fruits and vegetables for vitamins A, C, and antioxidants.

3. Whole grains and fiber (oats, brown rice) for regular bowel movements.

4. Calcium sources (milk, yogurt, fortified plant milk) for bones.

5. Healthy fats (olive oil, nuts, seeds) for energy and omega-3s.

What to avoid or limit:

1. Sugary drinks and sweets that displace nutrient-dense foods.
2. Ultra-processed snacks high in salt that may cause swelling.
3. Constipating patterns (low fiber, low fluids).
4. Herbal or “immune” products without pediatric approval.
5. Smoking exposure (second-hand smoke) which slows healing.

Frequently asked questions

1. Is this my fault?
   No. These differences occur very early in pregnancy. Parents do not cause them.

2. Will my child need surgery?
   Often yes for hypospadias and hand/foot differences. The team will time surgery for safety and best results.

3. Will my child have normal intelligence?
   Most children have typical thinking and learning. Some need help with fine-motor or speech. School supports can help a lot.

4. Is there a single gene that causes this?
   Sometimes, but not always. Genes like MID1 (midline development) or GLI3 (limb patterning) are examples in related conditions. Testing may or may not find a cause.

5. Will my child outgrow it?
   Structural differences do not disappear, but function can improve greatly with surgery and therapy.

6. Can vitamins cure the syndrome?
   No vitamin cures it. Nutrition and supplements support growth and healing.

7. Is stem cell therapy available?
   No approved stem cell or gene therapies exist for this syndrome. Avoid unregulated clinics. Consider only regulated clinical trials.

8. What is the success rate of hypospadias surgery?
   Most repairs heal well in experienced hands. Some children need a second stage or a small revision. Your surgeon will explain local outcomes.

9. Will my child be able to play sports?
   Usually yes, with gradual training and any needed adaptations. Avoid contact sports during post-op periods.

10. Can this happen again in the family?
    Sometimes. Genetic counseling can estimate recurrence risk based on testing and family history.

11. How do we prepare for surgery?
    Follow fasting rules, bring comfort items, and review pain and dressing plans. Ask all questions ahead of time.

12. What about scarring?
    Most scars soften over time. Massage, silicone, and sun protection help. Some children form thicker scars and may need extra support.

13. Will school understand?
    A written plan (IEP/504) explains needs and supports. Therapists can train staff.

14. Are there support groups?
    Yes. Your hospital social worker or genetic counselor can connect you to family networks and reputable organizations.

15. What is the long-term outlook?
    With coordinated care, most children grow, learn, and participate fully. Follow-up through adolescence helps address urinary, sexual, and psychosocial health.
