The Usher syndromes are autosomal recessive hereditary disorders characterized by hearing impairment and progressive visual loss due to Retinitis Pigmentosa (RP). Moderate to severe sensorineural hearing loss and progressive RP characterizes Usher syndrome type IIa (USH2A), which maps to the long ar

Usher syndrome is an autosomal recessive disorder characterized by congenital hearing impairment and retinitis pigmentosa. Three clinical types are known (USH1, USH2 and USH3), and there is an extensive genetic heterogeneity, with at least ten genes implicated. The most frequently mutated genes are
Three new mutations in the myosin VIIA gene involved in the pathogenesis of Usher syndrome type Ib are reported. These mutations are K1080X in exon 25, E1170K in exon 28, and Y1719C in exon 37. It is presumed that these mutations are involved in the Usher syndrome Ib phenotype.
## Communicated by Dvorah Abeliovich Recessive mutations of MYO7A, encoding unconventional myosin VIIA, can cause either a deaf-blindness syndrome (type 1 Usher syndrome; USH1B) or nonsyndromic deafness (DFNB2). In our study, deafness segregating as a recessive trait in 24 consanguineous families
