Cleft palate–coloboma–deafness syndrome is a very rare genetic condition seen at birth. Children have three core findings:
a cleft palate (an opening in the roof of the mouth),
an eye coloboma (a missing piece of eye tissue that looks like a gap or keyhole),
and hearing loss (deafness or hard-of-hearing).
What “coloboma” means: a gap in structures of the eye present from birth; vision can be normal, mildly reduced, or severely affected depending on the size/location (iris vs retina/optic nerve). Management focuses on vision optimization, protection from light/trauma, and addressing complications like retinal detachment if at risk. National Eye InstituteAmerican Academy of Ophthalmology
What “cleft palate” means: the hard/soft palate did not fully close before birth, which can affect feeding, speech, ear pressure and infections. Repair surgery (palatoplasty) is usually done in infancy, with ongoing speech and feeding therapy.
What “deafness” means here: hearing loss may be conductive, sensorineural, or mixed; it may require hearing aids, bone-anchored devices, or cochlear implants plus auditory-verbal therapy and educational supports. Similar ear problems are well documented in related syndromes (e.g., CHARGE, branchio-oculo-facial, Treacher Collins). NCBI+1EyeWikiSeattle Children’s
Some people also have other birth differences (for example in the urinary or genital system or bones). Doctors have described families with this triad since the 1970s, sometimes using the name Abruzzo–Erickson syndrome. It overlaps with other syndromes that also include coloboma and hearing loss (such as CHARGE and branchio-oculo-facial syndrome), so careful evaluation by genetics, ENT, ophthalmology and craniofacial teams is important to confirm the exact diagnosis and to guide care. PubMedOrphaNCBI+1MedlinePlus
Doctors first described this pattern in 1977 in a family with several affected members. In that report, some relatives also had short stature, radioulnar (forearm) bone fusion, and, in males, hypospadias (a urinary opening on the underside of the penis). Because of the full set of findings, the original authors suggested an X-linked inheritance pattern (passed through the X chromosome). Today, many experts refer to this condition as Abruzzo–Erickson syndrome (ABERS). PMCBMJ Journals
Modern genetics has linked ABERS to changes in the TBX22 gene, a transcription factor that guides normal facial and palate development. TBX22 variants are a known cause of X-linked cleft palate (CPX) and ankyloglossia (tongue-tie). Some families with the classic triad of cleft palate, coloboma, and deafness also carry TBX22 variants, supporting the idea that ABERS sits on the broader TBX22-related spectrum. The inheritance is typically X-linked recessive (males more affected; females may be mildly affected carriers). PubMedGenetic Diseases Info CenterOrphaMouse Genome Informatics
Important context: other, better-known syndromes can also combine coloboma, clefting, and hearing loss, especially CHARGE syndrome (usually due to CHD7 variants), Baraitser–Winter cerebrofrontofacial syndrome (ACTB/ACTG1 variants), and Lenz microphthalmia syndrome (BCOR variants). Doctors therefore rule out these conditions first, then consider ABERS/TBX22 when the pattern fits and CHD7/ACTB/ACTG1/BCOR testing is negative or family history suggests X-linkage.

Types
There is no official, universally accepted medical subtype list for this syndrome. Clinicians often use practical groupings to guide evaluation and counseling:
Classic ABERS
Individuals show the triad (cleft palate, ocular coloboma, mixed hearing loss) and may also have short stature, radioulnar synostosis, and (in males) hypospadias. Often X-linked family history. PMCPartial/attenuated ABERS
People have two of the three key features (for example, cleft palate and hearing loss without obvious coloboma) plus soft signs such as bifid uvula, high-arched palate, ear shape differences, or mild eye findings. This pattern is seen in some TBX22 families because the phenotype can be variable. PubMedTBX22-related orofacial cleft spectrum with ocular/ear features
Families primarily known for X-linked cleft palate/ankyloglossia may also include individuals with coloboma and/or hearing loss, suggesting a spectrum anchored in TBX22 biology. PubMed“CHARGE-like” differentials
When the triad appears with additional features (choanal atresia, semicircular canal hypoplasia, cranial nerve dysfunction), CHARGE syndrome (CHD7) is more likely; ABERS usually lacks choanal atresia and genital hypoplasia that are common in CHARGE. This “type” is really a diagnostic bucket used before genetic results are back. EyeWiki
Causes
ABERS the main known cause is a change (variant) in the TBX22 gene. Other entries below describe how different genetic changes or developmental influences can produce a similar trio of problems (important for the differential diagnosis). I’ll note when a cause is core to ABERS versus look-alike.
TBX22 loss-of-function variant (core ABERS cause)
A spelling change that stops TBX22 working can disrupt palate formation and related head/neck structures, leading to cleft palate; hearing loss can be sensorineural, conductive, or mixed; and eye development can be affected, producing coloboma. TBX22 is on the X chromosome, explaining the usual X-linked pattern. PubMedOrphaTBX22 splice-site variant (core)
A change that alters how the gene’s message is cut and pasted can reduce functional protein and widen the phenotype beyond isolated cleft palate toward the ABERS triad in some families. PubMedTBX22 missense variant with reduced DNA binding (core)
A single amino-acid swap can weaken TBX22’s control of downstream genes, sometimes producing milder or variable features within a family. ScienceDirectLarge deletion/duplication involving TBX22 (core/suspected)
Copy number changes that remove or disrupt TBX22 (or its regulatory elements) can mimic other TBX22 variants; clinical labs look for these when sequencing is negative. (Mechanism inferred from TBX22 disease biology.) NCBICHD7 variant (look-alike: CHARGE syndrome)
When the triad occurs with choanal atresia, distinctive ear anomalies, or cranial nerve problems, a CHD7 variant is often found—pointing to CHARGE rather than ABERS. NCBIEyeWikiACTB or ACTG1 variants (look-alike: Baraitser–Winter)
These actin genes can cause facial differences, coloboma, and sensorineural hearing loss; clefting may be present. NCBIMedlinePlusBCOR variant (look-alike: Lenz microphthalmia)
An X-linked condition in which microphthalmia/coloboma, hearing loss, and sometimes cleft palate occur; this can mimic ABERS in boys. PMCRare DiseasesPAX2 variant (look-alike: renal-coloboma)
Causes optic nerve coloboma; cleft palate and deafness are less typical, but hearing issues can occur; kidney findings help distinguish it. PubMedYAP1, OTX2, PAX6, SOX2 variants (look-alike: ocular coloboma spectrum)
These eye-development genes can produce coloboma plus craniofacial anomalies; some affected people also have hearing problems. (Grouped here as an eye-development differential.) Genetic Diseases Info CenterGDF6 or GDF3 variants (look-alike)
Growth-factor gene changes linked to ocular coloboma and skeletal anomalies; clefting/hearing issues vary. Genetic Diseases Info CenterRBP4, MAB21L2, FZD5, ABCB6 variants (look-alike)
Additional, rarer coloboma genes reported in cohorts with mixed ocular/craniofacial features. Genetic Diseases Info CenterChromosomal rearrangement near TBX22 (suspected)
A structural change on Xq21.1 that disrupts TBX22 regulation may recapitulate ABERS; labs use microarray if sequencing is unrevealing. (Diagnostic practice summary.) NCBINew (de novo) TBX22 variant
Not inherited from either parent; explains an isolated case without family history, though X-linkage often shows familial patterns. Genetic Diseases Info CenterModifier genes
Even within the same family, the look of the condition can differ; background genes likely modify TBX22 effects, explaining variability from bifid uvula to full cleft palate with added features. PubMedMaternal diabetes (look-alike risk factor)
Increases risk of clefting and some eye/ear anomalies in the population; if genetic testing is negative, clinicians consider prenatal exposures. (General teratology principle; used in differential reasoning.) — (no single ABERS study)Retinoic acid exposure (look-alike risk factor)
Can cause craniofacial and ear malformations; considered in history-taking but does not explain X-linked inheritance. — (teratology background)Folate deficiency (population risk for clefting)
Low folate raises risk of clefting broadly; supplementation is preventive at the population level but does not remove an X-linked TBX22 variant. — (public-health evidence)Consanguinity (pattern amplifier)
Not a cause of X-linked ABERS itself, but can increase the chance that rare variants (including in coloboma/hearing genes) appear in a family, complicating the diagnostic picture. — (genetic counseling principle)Undetected regulatory variant of TBX22 (core/suspected)
Changes in non-coding switches that control TBX22 may explain some clinically convincing cases with negative gene tests. (Mechanistic inference from other clefting genes.) ScienceDirectUnknown/undiscovered gene (research frontier)
A small number of families with the ABERS triad do not yet have a pinpointed molecular cause; research and broader sequencing can help. PMC
Common signs and symptoms
Cleft palate
An opening in the roof of the mouth that can cause nasal milk regurgitation, feeding trouble, ear infections, and speech problems. In ABERS it ranges from submucous/bifid uvula to a complete cleft. NCBIBifid uvula / high-arched palate
Mild palate changes that still affect speech and ear pressure; they are part of the TBX22 spectrum and may be clues in female carriers. NCBIColoboma of iris, retina, or optic nerve
A notch or gap in eye structures formed early in pregnancy; vision impact depends on location and size. PMCMixed hearing loss (sensorineural + conductive)
Inner-ear nerve damage plus middle-ear issues can both be present; severity varies, and some people need hearing aids or implants. OrphaEar shape differences (macrotia, unusual folds)
These “soft signs” support a syndromic cleft rather than an isolated cleft. MalaCardsShort stature
Reported in the original family; growth tracking helps decide if endocrine or skeletal evaluation is needed. PMCRadioulnar synostosis (forearm bones fused)
Limits forearm rotation; strength and function can improve with therapy and, rarely, surgery. PMCHypospadias (in males)
The urinary opening is not at the tip; pediatric urology evaluates for timing of repair. PMCFacial differences (malar flattening, broad nasal bridge, asymmetry)
Subtle facial features help clinicians recognize a pattern. MalaCardsDental anomalies
Tooth shape/spacing problems can complicate feeding and speech; coordinated dental/orthodontic care is helpful. MalaCardsWide spacing between the 2nd and 3rd fingers
A minor skeletal sign described in summaries of ABERS. NCBIVision problems (blurred vision, field defects, light sensitivity)
Direct consequences of coloboma; severity depends on which eye structures are involved. PMCRecurrent ear infections / eustachian tube dysfunction
Common with cleft palate because of muscle imbalance; this may worsen conductive hearing loss. (Cleft palate physiology principle)Speech resonance problems (hypernasality)
Air escapes through the nose during speech; speech-language therapy and sometimes surgery improve clarity. (Cleft care standard)Generally normal intelligence
Unlike classic CHARGE, intellectual disability is not a defining feature of ABERS; many individuals attend mainstream school with targeted supports. Wikipedia
Diagnostic tests
A) Physical examination
Newborn and infant general exam
Checks growth, facial shape, breathing, and feeding. Early recognition triggers specialist referrals. PMCOral cavity and palate exam

Looks for ear canal shape, eardrum status, and fluid; helps sort conductive from sensorineural hearing loss. (ENT standard)Musculoskeletal exam of the upper limbs
Screens for limited forearm rotation suggesting radioulnar synostosis; if suspected, imaging follows. PMC
B) Manual / bedside tests
Tuning-fork hearing tests (Rinne and Weber)
Quick bedside checks in older children/adults to separate conductive from sensorineural hearing loss before full audiology testing. (ENT basics)Cover–uncover test and ocular motility exam
Detects strabismus or ocular movement limits that can accompany coloboma or microphthalmia. (Ophthalmology practice)Velopharyngeal function assessment during speech

Objective hearing test for infants/young children who cannot do behavioral audiograms yet. (Pediatric audiology standard)
E) Imaging tests
Ocular imaging (fundus photography and OCT)
Documents the size and depth of the coloboma and checks the macula/optic nerve for complications that affect vision. (Ophthalmology practice)Forearm X-ray / CT
Confirms radioulnar synostosis, helping orthopedic planning and therapy. PMCTemporal bone CT (selected cases)
Maps middle- and inner-ear anatomy, especially if surgery or implants are considered. (ENT practice)Brain MRI (if seizures or neurologic signs)
Not routine for ABERS, but done when symptoms point to central causes of hearing/vision problems or to exclude look-alike syndromes. UniqueRenal ultrasound (differential check)
Performed when PAX2-related renal-coloboma is in the differential or if urine tests show blood; helps rule in/out other syndromes. PubMedEchocardiogram (if clinical signs)
Heart defects are a major feature of CHARGE but not a defining feature of ABERS; an echo is considered if murmurs/cyanosis are present to help separate diagnoses. NCBINasoendoscopy (velopharyngeal imaging during speech)
A small flexible camera shows how the soft palate and throat close during speech to plan surgery for hypernasality. (Cleft team standard)

Evidence context: The drug choices above follow standard pediatric pathways for complications (AOM, rhinitis, reflux, post-operative care) common in cleft palate and ear disease; specific regimens are tailored by the child’s specialists. Coloboma itself is not “medically treated,” but ocular surface comfort and protection are important. For the core condition there is no disease-specific curative medicine at present. National Eye InstituteCleveland Clinic
Dietary “molecular” supplements
(Always confirm safety with the child’s clinician; doses are examples and may vary by age/weight.)
Omega-3 fatty acids (fish oil or algal DHA) – supports retinal/neuronal development and may help inflammation; typical child doses vary by product.
Vitamin A (with caution; avoid excess) – essential for the retina; only to correct deficiency; excess can harm the liver/vision.
Lutein/zeaxanthin – macular pigments that support visual function; used cautiously; helpful in some eye conditions.
Vitamin D – correct deficiency; supports immunity and bones.
Calcium – with vitamin D for bone health when intake is low.
Iron – only if deficient; improves energy and cognition.
Zinc – supports wound healing post-surgery when dietary intake is low.
B-complex (including B12/folate as indicated) – for general metabolic support when dietary variety is limited.
Probiotics – may reduce antibiotic-associated diarrhea.
Multivitamin (age-appropriate) – fills small gaps when feeding is restrictive.
Note: Supplements do not replace surgery, hearing devices, or therapies; they only support overall health and healing. For coloboma specifically, optical and protective strategies matter far more than nutrients. National Eye Institute
Regenerative / stem-cell” drug concepts
There are no approved “immunity booster,” regenerative, or stem-cell drugs that treat this syndrome or “regrow” missing eye or palate tissues. Research areas exist, but they are experimental:
Inner-ear hair-cell regeneration (preclinical/early trials in sensorineural deafness) – not approved for children with genetic syndromic hearing loss.
Retinal cell or RPE transplantation for coloboma-related retinal gaps – conceptual; coloboma is a developmental absence rather than a degenerative loss.
Gene therapy/editing (e.g., CHD7 for CHARGE) – research stage; not available clinically. NCBI
Tissue-engineered palate scaffolds – future concept; current standard is surgical repair.
Exosome-based therapies – experimental only.
Immunoglobulin therapy – only if a documented immune deficiency is present (recognized in some CHARGE patients), not for the triad in general. PubMed

New or persistent ear pain, fever, or ear drainage.
Hearing changes (less response to sound, device problems).
Feeding trouble, choking, vomiting blood, or poor weight gain.
Breathing issues during sleep or while feeding.
Eye pain, sudden flashes/floaters, a curtain-like shadow, or trauma to the eye.

Any developmental regression or school difficulties.
Before starting supplements or new therapies.
What to eat and what to avoid
What to eat
Texture-appropriate foods advised by your feeding therapist (purees → soft solids → regular textures as safe).
Protein-rich meals (eggs, dairy/yogurt, fish, beans, poultry) to support growth and wound healing.
Fruits/vegetables prepared to safe textures; include leafy greens and orange/yellow veg for eye-friendly nutrients.
Healthy fats (olive oil, nut butters if age-safe, avocado) for calories and brain health.
Hydration (water, milk if tolerated).
Vitamin-D and calcium sources (dairy/fortified alternatives, fish).
What to avoid or limit
Hard, sharp, or sticky foods early after palatoplasty (chips, hard candies, chewy caramels).
Very spicy/acidic foods if they trigger reflux symptoms.
Sugary drinks that worsen dental risk.
Secondhand smoke (ear and airway complications).
Excess vitamin A supplements without medical advice.
Frequently asked questions
Is there a cure?
No single cure exists. Care focuses on repairing the palate, optimizing vision/hearing, and supporting development with therapy.Is it the same as CHARGE syndrome?
Not exactly. The triad overlaps with CHARGE and a few other syndromes, so genetics and specialist exams help tell them apart. NCBIMedlinePlusWill my child speak normally after surgery?
Many children achieve clear speech with palatoplasty plus long-term speech therapy. Early intervention matters.Can coloboma be fixed with drops?
No. Eye drops help comfort, but coloboma is a structural gap. Protection, optical correction, and monitoring prevent complications. National Eye InstituteIs hearing loss permanent?
It can be conductive, sensorineural, or mixed. Many children improve with tubes, hearing aids, or cochlear implants plus therapy.Will my child have normal intelligence?
Most children have normal intelligence, though speech/hearing/vision challenges can affect school; supports and accommodations help. NCBIDo we need genetic testing?
Often yes. It clarifies the diagnosis, guides screening for associated problems, and informs family planning. Rare DiseasesWhat complications should we watch for in the eyes?
Glare/photophobia, refractive errors, and rare risk of retinal issues depending on coloboma location—prompt eye care if new symptoms. National Eye InstituteHow soon is palate surgery?
Timing is individualized by the craniofacial team, often within the first year of life to support feeding and speech.Are vaccines safe?
Yes—routine vaccines are important to reduce ear and airway infections.What about nutrition shakes?
They can help meet calories/protein if advised by your feeding team; choose age-appropriate products.Can school supports be formalized?
Yes—through IEP/504 (or local equivalents). Include hearing/vision accommodations and speech therapy.Is there a role for gene therapy now?
Not currently for this triad; research continues for related genetic conditions. NCBIWill my child need multiple surgeries?
Often yes (palate repair, possible ear tubes; occasionally cochlear implant; selected eye procedures). Care is staged and planned.How do we cope with the care load?
