Involvement in diseasei

Ectodermal dysplasia 2, Clouston type (ECTD2)2 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of ectodermal dysplasia, a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures such as hair, teeth, nails and sweat glands, with or without any additional clinical sign. Each combination of clinical features represents a different type of ectodermal dysplasia. ECTD2 is an autosomal dominant condition characterized by atrichosis, nail hypoplasia and deformities, hyperpigmentation of the skin, normal teeth, normal sweat and sebaceous gland function. Palmoplantar hyperkeratosis is a frequent feature. Hearing impairment has been detected in few cases.

Deafness, autosomal recessive, 1B (DFNB1B)2 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information.
See also OMIM:612645
Deafness, autosomal dominant, 3B (DFNA3B)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA form of non-syndromic sensorineural hearing loss characterized by a variable phenotype, ranging from bilateral middle to high frequency hearing loss to profound sensorineural deafness. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information.
