Chudley-McCullough syndrome is an autosomal recessive neurologic disorder characterized by early-onset sensorineural deafness and specific brain anomalies on MRI, including hypoplasia of the corpus callosum, enlarged cysterna magna with mild focal cerebellar dysplasia, and nodular heterotopia. Some patients have hydrocephalus. Psychomotor development is normal (summary by Alrashdi et al., 2011). [from OMIM]

An autosomal recessive disorder caused by mutations in the TRIOBP gene, encoding TRIO and F-actin-binding protein. The condition is characterized by severe to profound sensorineural hearing loss. [from NCI]

Branchial arch abnormalities, choanal atresia, athelia, hearing loss, and hypothyroidism syndrome (BCAHH) is an autosomal dominant disorder characterized by choanal atresia, athelia or hypoplastic nipples, branchial sinus abnormalities, neck pits, lacrimal duct anomalies, hearing loss, external ear malformations, and thyroid abnormalities. Additional features may include developmental delay, impaired intellectual development, and growth failure/retardation (summary by Cuvertino et al., 2020 and Baldridge et al., 2020). [from OMIM]

An exceedingly rare genetic disorder with characteristics of cutaneous pigmentation anomalies, ocular disorders and hearing loss. The syndrome was described in 1990 in two patients from the same Yemenite family. A brother and sister were described as having cutaneous patchy hypo and hyperpigmentation on the trunk and extremities, gray hair, white brows and lashes. Ocular manifestations were microcornea, coloboma and abnormalities of the anterior chamber of the eye. Both patients had severe hearing loss and dental abnormalities. Intelligence was reported to be normal. Their parents were unaffected and possibly consanguineous. The cause of this syndrome has not been determined. The inheritance pattern appears to be autosomal recessive. [from SNOMEDCT_US]
