Acrocraniofacial dysostosis (often shortened to ACFD) is an extremely rare inherited condition that mainly affects how the skull, face, ears, and some bones of the body form before birth. In simple words, parts of the head and face grow in an unusual way. Some children may also have changes in the hands or feet, the chest wall, and the way the ears and hearing system work. Doctors have described only a very small number of people with this exact diagnosis in the medical literature, which means information is limited and still growing. Typical features that have been reported include a tall, pointed head shape (acrocephaly), eyes that are widely spaced, droopy eyelids, eyes that look prominent, a high nasal bridge with up-tilted nostrils, a short groove between the nose and upper lip, a small lower jaw, cleft palate, unusual outer ears with small skin pits in front of them, hearing problems, broad or “bulbous” finger or toe tips, inward-turned feet, a sunken chest (pectus excavatum), and other bone differences.

Acrocraniofacial dysostosis (ACFD) is an extremely rare genetic condition that affects how the skull and face form (cranio-facial), and may also affect the bones of the hands and feet (acro-). Only a very small number of people have been described in the medical literature—historically two sisters in a single family—so doctors have limited data. The main features reported include a tall, cone-shaped skull (acrocephaly), wide-set eyes, droopy eyelids, bulging eyes, a short groove between the nose and upper lip, small lower jaw, cleft palate, unusual external ears, small skin pits in front of the ears, and mixed (conductive and sensorineural) hearing loss. Some people may have broad or “bulbous” fingertips or toes and chest wall differences such as pectus excavatum. Because so few cases exist, there is no single standard treatment; care focuses on the person’s specific needs using a team approach (genetics, craniofacial surgery, ENT/audiology, ophthalmology, dentistry/orthodontics, speech/feeding therapy, orthopedics, and rehabilitation). Orpha.netGenetic Rare Diseases CenterPharosMonarch InitiativePubMed
Because so few cases are known, experts sometimes explain ACFD by comparing it to the wider family of acrofacial dysostoses—conditions that combine face/skull changes with limb or other skeletal differences—and to craniofacial dysostoses, where many skull sutures and mid-face bones are involved. These related groups help doctors think about causes, testing, and care plans even when exact research on ACFD is scarce. PMCPubMed
Other names
Kaplan–Plauchu–Fitch syndrome (a synonym used in medical summaries).
Acrocraniofacial dysostosis (ACFD) (preferred descriptive name).
These labels refer to the same very rare condition noted above. Published summaries also emphasize how few individuals have been formally reported. WikipediaMalaCards
Why this happens
During early pregnancy, cells that build the skull, face, and parts of the ear and skeleton must migrate, grow, and join together in a very precise way. If the “genetic instructions” that guide these steps are disrupted, bones and soft tissues can form with different shapes or positions. Scientists studying the facial/acrofacial dysostosis group have shown that problems during neural crest cell development (the cell population that forms much of the face) and first/second pharyngeal arch development can lead to these patterns. For this specific disorder (ACFD), a single cause gene has not been clearly established yet because so few people have been studied. Instead, doctors use knowledge from related conditions to guide evaluation. PMC
Types
Because ACFD is ultra-rare and formal, gene-based subtypes are not established, a useful way for families and clinicians to organize care is to group people by their main clinical focus. These are pragmatic (clinic-useful) groupings rather than official scientific subtypes:
Cranio-orofacial–predominant type
Head and face changes are the most visible concerns (head shape, eyelids, palate, jaw). Hearing and ribs/limbs are mildly affected or normal.Oto-craniofacial type
The face/skull features occur together with significant ear and hearing problems (mixed or conductive hearing loss), so early hearing support is central to care. Orpha.netSkeletal-accented type
Face/skull changes are present along with notable skeletal findings such as chest wall changes (pectus excavatum), inward-turned feet, or bulbous digits requiring orthopedics/physiotherapy. Orpha.netComplex/multisystem type
Several areas (face/skull, hearing, chest wall, digits/feet) all need attention from a coordinated team.
Note: These “types” help plan support and follow-up. They are not official genetic classes, because the condition is too rare for that today.
Causes
Important context: For ACFD specifically, a single confirmed cause gene has not been pinned down in the literature. What follows are cause categories that are plausible and relevant based on how closely related craniofacial/acrofacial dysostoses work. They explain how development can be disturbed—not that each has been proven in ACFD itself.
New (de novo) genetic change
A one-time change in an embryo’s DNA that neither parent has can alter skull/face development programs. This is common across many rare craniofacial syndromes. PubMedInherited genetic change with variable expression
A parent may carry a mild or silent form, while a child shows a fuller picture because of how the same change acts differently in different people. PubMedDisruption of neural crest cell migration
If these facial “builder cells” can’t travel or survive correctly, midface and ear structures may form differently. PMCDisturbed first/second pharyngeal arch signaling
Early jaw, ear, and palatal tissues rely on precise molecular signals; noise in these signals can change final shape. PMCAltered cranial suture timing
If skull sutures close too early (craniosynostosis pathways), head shape and facial growth vectors change. PubMedChromatin/remodeling pathway effects
Some facial syndromes arise when “DNA packaging” and gene-on/gene-off controls misfire during organ formation. (This is a general mechanism seen in related dysostoses.)Splicing/transcription pathway effects
In related acrofacial dysostoses, genes that control RNA processing are involved; altered splicing can change many downstream proteins at once. PMCOssification pathway imbalance
Signals that tell cartilage to become bone must be balanced; imbalance can create unusual bone contours or timing.Apoptosis (cell pruning) errors
Some tissues must thin or separate during development; if pruning is off, webs or unusual shapes can appear.Ear and temporal-bone morphogenesis errors
Developmental mis-steps around the middle/inner ear can produce mixed hearing loss. Orpha.netExtracellular matrix/adhesion changes
If tissues do not stick and remodel properly, facial contours may not form as expected.Vascular patterning differences
Blood vessel layout guides bone and cartilage growth; unusual patterns can subtly redirect growth.Cilia/signaling hub defects (theory from related syndromes)
Some craniofacial syndromes involve cilia; disturbed ciliary signals can misguide facial patterning.Gene–environment interactions (rarely)
Most cases are genetic, but nutritional or metabolic stresses early in pregnancy can influence severity.Modifier genes
Extra genetic changes can make a main change milder or more severe, explaining differences between people.Somatic mosaicism
A change occurring after the first cell divisions may affect some body parts more than others, leading to uneven findings.Epigenetic shifts
Chemical tags on DNA that control gene use (without changing the letters) can alter development programs.Pathways shared with craniofacial dysostosis
Mechanisms known in craniosynostosis families (e.g., suture biology) may overlap with ACFD patterns. PubMedPathways shared with acrofacial dysostoses
Research on the broader AFD group continues to reveal common developmental routes that could apply to ACFD. PMCCurrently unknown factor
With only a handful of published cases, an as-yet-unknown gene or pathway may be central to ACFD. Ongoing exome/genome testing in families may clarify this in the future. Wikipedia
Common symptoms and signs
These are drawn from published summaries of ACFD; an individual child will not have all of them, and the severity varies. Orpha.netPharos
Acrocephaly (tall, peaked head shape)
The skull grows upward more than usual. This can make the head look high or pointed on top.Wide-set eyes (ocular hypertelorism)
The distance between the eyes is larger than average, creating a broad look to the upper face.Droopy eyelids (ptosis)
The upper eyelids sit lower than normal, which can partly cover the pupils and reduce vision if severe.Prominent eyes (proptosis/exophthalmos)
The eyes appear to sit forward. This can be due to tight bones around the sockets.Down-slanting eyelid openings
The outer corners of the eyes are lower than the inner corners, changing the eye shape.High nasal bridge with up-tilted nostrils (anteverted nares)
The nose looks high at the top and the nostrils point slightly upward.Short philtrum
The groove between the nose and the upper lip is shorter than usual.Cleft palate
There is a gap in the roof of the mouth, which can cause feeding and speech problems.Small lower jaw (micrognathia)
The chin is small and set back. This can crowd the tongue and affect breathing in infancy.Unusual outer ears
The ear shape is different, and there may be small pits of skin in front of the ears (preauricular pits).Hearing loss (often mixed)
Both the sound-conducting parts and the inner ear may be affected, so hearing aids or other devices may help. Orpha.netShort stature
The child’s overall height is below average for age and sex.Bulbous finger or toe tips
The ends of the digits look rounded and full.Inward-turned feet (metatarsus varus)
The front of the foot points inward; stretching, special shoes, or casting may be used.Sunken chest (pectus excavatum)
The breastbone is caved inward. Mild cases may be only cosmetic; severe cases can affect exercise tolerance. Orpha.net
Diagnostic tests
Because ACFD is ultra-rare, testing aims to
A) Physical examination
Detailed dysmorphology exam
A clinical geneticist measures head size and shape, eye distance, ear position, jaw size, palate, chest, hands/feet, and spine. Careful notes and standardized photos guide follow-up and surgery planning. (This is core to all dysostoses.) PMCCranial suture palpation and head-shape mapping
The doctor gently feels the skull sutures and fontanelle and documents head shape (e.g., acrocephaly). If sutures feel tight or closed early, imaging is considered. PubMedAirway and feeding assessment
Small jaws and cleft palate can affect breathing and feeding. Bedside checks look for noisy breathing, retractions, poor weight gain, and signs of airway obstruction.Vision screening
Ptosis and proptosis can reduce vision or cause dry eyes. Doctors check eye movements, surface moisture, and whether pupils are fully uncovered.Growth and nutrition review
Height/weight charts and feeding history help track short stature or feeding issues and direct nutrition support.
B) Manual/bedside tests
Anthropometric measurements
Exact distances (inner/outer canthal, interpupillary) and angles are measured to document wide-set eyes and eyelid slant. This creates a baseline for later comparison.Bedside hearing screens (otoacoustic emissions or simple response tests)
Quick, noninvasive checks flag the need for full audiology. Early detection supports language development.Cleft palate functional exam
A speech-language pathologist (SLP) listens for nasal air escape and checks feeding/suck; this helps decide on timing of palatal repair.Orthopedic foot evaluation
Gentle range-of-motion tests and “forefoot adduction” grading help decide on stretching, splints, or casting for metatarsus varus.
C) Laboratory and pathological tests
Chromosomal microarray (CMA)
Looks for missing or extra DNA segments across the genome. It is a first-line genetic test for complex birth differences.Clinical exome or genome sequencing
Reads the coding (or entire) DNA to search for rare variants in genes known to shape facial/cranial development; also useful for discovering new genes in ultra-rare disorders like ACFD. (Genomic testing underpins work in the craniofacial/acrofacial dysostosis field.) PMCParental studies (trio testing)
Testing parents clarifies if a variant is new (de novo) or inherited, which helps with recurrence risk counseling.Basic metabolic and endocrine screen (as needed)
Calcium/phosphate, vitamin D, thyroid, and other labs are sometimes checked to rule out conditions that can mimic or worsen skeletal findings.Hearing-related labs (selective)
If there is repeated ear infection or drainage, cultures and inflammatory markers may guide ENT care (not a cause test, but supports hearing management).
D) Electrodiagnostic tests
Diagnostic audiology with ABR (auditory brainstem response)
Objective testing defines the type and degree of hearing loss (conductive, sensorineural, or mixed) to guide hearing aids or other devices. Orpha.netTympanometry and acoustic reflexes
Measures eardrum movement and middle ear status; useful when outer/middle ear anatomy is unusual.Polysomnography (sleep study) if airway concerns
Children with small jaws or midface hypoplasia can have sleep-disordered breathing; overnight testing quantifies severity and directs therapy.
E) Imaging tests
Low-dose CT (or 3-D CT) of skull and cranial base (judicious use)
Defines skull shape, sutures, and orbital bones for surgical planning in craniofacial dysostosis patterns; used carefully to minimize radiation in children. PubMedTemporal-bone CT and/or MRI (if significant hearing loss)
Looks for middle/inner ear structural differences that may explain mixed hearing loss and inform ENT procedures. Orpha.netSkeletal radiographs targeted to findings
X-rays of hands/feet (bulbous tips), feet alignment (metatarsus varus), and chest (pectus excavatum) help orthopedics plan braces, therapy, or surgery. Orpha.net

Caution: Iron-containing versions need safe storage.Selenium (only if low) – Antioxidant enzyme support.
Dose: Small, diet-based; supplement only with guidance.
Caution: Hair/nail issues if excessive.
Regenerative / stem-cell drugs
There are no approved immune “booster,” regenerative, or stem-cell drugs for ACFD. Using stem cells or intensive immune-modulating products outside clinical trials can be risky and unethical. If you are interested in research, ask your genetics team about registered clinical trials or natural-history studies; these help doctors learn safely without false promises. Safer, evidence-based ways to protect health include vaccination, nutrition, sleep, and prompt treatment of ear/eye problems. (This caution reflects the extreme rarity of ACFD and the absence of disease-specific drug trials.) Orpha.netMonarch Initiative
Surgeries
Palatoplasty (cleft-palate repair)
Procedure: Surgical closure of the palate, often at 9–18 months depending on center.
Why: Improve feeding, speech, and reduce ear infections by restoring palatal function.Ptosis repair / eyelid procedures and temporary tarsorrhaphy (if exposure)
Procedure: Tighten or reposition eyelid muscles; temporary partial eyelid closure in severe exposure.
Why: Protect the cornea from drying and scarring that can threaten vision. (Eye exposure risk is recognized in craniosynostosis patterns.) MedlinePlusTympanostomy tubes
Procedure: Tiny tubes placed in the eardrum.
Why: Ventilate the middle ear, reduce infections, and improve hearing to support speech/language.Mandibular distraction osteogenesis or later orthognathic surgery
Procedure: Gradual bone lengthening (childhood) or jaw alignment surgery (adolescence/adult).
Why: Enlarge airway, improve bite, speech resonance, and facial balance.Orthopedic/foot corrective procedures (case-by-case)

Prevention and protection steps
Genetic counseling for families planning future pregnancies (discussion of testing options). Orpha.net
Prenatal/early postnatal planning with a craniofacial center for airway and feeding readiness.
Safe sleep and apnea screening if snoring, pauses, or restless sleep.
Eye protection habits (lubrication, protective glasses, prompt care for irritation). MedlinePlus
Hearing protection and early audiology follow-up to avoid language delay. Orpha.net
Dental prevention (fluoride, regular cleanings, early orthodontic consult).

Good hand hygiene to limit respiratory infections after surgeries.
Nutrition and growth monitoring with a dietitian, especially around surgeries.
Injury prevention (fall safety, eye safety, sun protection for scars).
When to see a doctor urgently vs. routinely
Urgent: Trouble breathing, bluish lips, pauses during sleep; eye pain/redness/light sensitivity (possible corneal injury); high fever or ear drainage with severe pain; dehydration from poor feeding; new weakness or worsening pain after surgery.
Soon (days–weeks): Noisy snoring or daytime sleepiness; feeding struggles, poor weight gain; frequent ear infections or hearing concerns; persistent eye dryness; speech that is very nasal or hard to understand; dental crowding or mouth pain.
Routine: Genetics follow-up, scheduled craniofacial clinic visits, audiology checks, vision checks, dental cleanings, and growth/nutrition review.
What to eat and what to avoid
Eat: Soft, high-protein foods after mouth/palate procedures (eggs, yogurt, dal, fish, tofu).
Eat: Colorful fruits/vegetables for vitamins A/C/K (eye, skin, wound healing).
Eat: Dairy or fortified alternatives plus leafy greens for calcium.
Eat: Foods rich in vitamin D (fortified milk, egg yolk) and get safe sunlight as advised.
Eat: Whole-grain carbohydrates and healthy fats (olive oil, nuts if safe) for energy.
Avoid: Very hard, sharp, or sticky foods soon after oral surgery (chips, hard candies).
Avoid: Excess sugary drinks that raise cavity risk.
Avoid: Known reflux triggers if symptomatic (large late meals, acidic/spicy foods).
Avoid: Unregulated supplements or “stem-cell” products sold online.
General: Hydrate well; involve a pediatric dietitian for growth plans.
Frequently asked questions
Is ACFD the same as Nager or Miller syndrome?
No. They are different conditions within the acrofacial dysostosis group. Nager (often linked to SF3B4) and Miller (linked to DHODH) have more published cases; ACFD is ultra-rare. PubMedMalaCardsPMCHow rare is ACFD?
Exceptionally rare; the original description involved two sisters. PubMedMonarch InitiativeWhat causes ACFD?
A specific gene has not been firmly established in public sources; inheritance in the first report suggested a familial pattern. Genetic evaluation can look for known craniofacial genes and copy-number changes. PubMedCan it be cured?
There is no cure; treatment addresses each problem (airway, feeding, hearing, eyes, teeth, jaw alignment). Orpha.netWill my child need surgery?
Many children with similar craniofacial features need one or more surgeries (e.g., palate repair, ear tubes, eyelid/eye protection, jaw procedures). Plans are individualized.Will hearing improve?
Hearing can often be improved with tubes, hearing aids, or bone-anchored devices plus therapy. Early audiology is important. Orpha.netAre vision problems common?
Bulging eyes and eyelid droop may increase the risk of dry or exposed eyes; eye lubrication and sometimes eyelid procedures help protect vision. MedlinePlusIs speech affected?
Cleft palate or jaw/ear issues can affect speech; early speech-language therapy and, when needed, palate surgery can help.What about growth and nutrition?
Feeding therapy, specialty bottles, and dietitian support help babies gain weight safely.Can regular schooling work?
Yes—with accommodations (front-row seating, FM system, individualized education plan) many children progress well. Audiology and speech input are key.Is pain long-term?
Not necessarily. Pain is usually short-term around procedures and managed with simple medicines.Are vaccines safe?
Yes—follow routine schedules unless your clinician says otherwise.Should we avoid contact sports?
Discuss case-by-case. If eye exposure or skull shape issues exist, protective eyewear/helmets and activity choices reduce risk.Are “stem-cell” treatments available?
No approved stem-cell or regenerative drugs exist for ACFD; beware of unregulated clinics. Consider only registered clinical studies after genetics consultation. Orpha.netWhere can we get coordinated care?
Craniofacial centers (often at children’s hospitals) provide team care—genetics, craniofacial surgery, ENT/audiology, ophthalmology, dentistry/orthodontics, speech/swallow therapy, nutrition, and psychology. (This is the model used for complex craniofacial disorders in general.) PubMed
