Frequent clinical manifestations include congenital sensorineural deafness, heterochromic or hypoplastic blue irides, white forelock or early graying of the scalp hair before the age of 30 years. The disease is genetically heterogeneous. To date, mutations in 6 different genes have been identified: PAX3 (2q36.1), MITF (3p14-p13), SNAI2 (8q11.21), SOX10 (22q13.1), EDNRB (13q22.3), and EDN3 (20q13.32). |

| A rare congenital ectodermal disorder characterized by vascularizing keratitis, hyperkeratotic skin lesions and hearing loss. Patients usually present at birth with generalized erythema and ichthyosiform scaling. The skin manifestations are progressive with erythrokeratoderma characterized by well-demarcated erythematous and keratotic plaques with a verrucous appearance predominantly located on the face, scalp, ears, elbows and knees. Hearing loss is congenital, usually sensorineural and is often profound. Caused by mutations involving the N-terminus and first extracellular loop of the GJB2 gene (13q11-q12), encoding connexin-26. Most of the reported cases are sporadic, but familial cases with autosomal dominant inheritance have been reported. |
