Further refinement of the Usher 2A locus at 1q41.
Usher syndrome (USH) is characterised by congenital sensorineural hearing loss and progressive pigmentary retinopathy. All three subtypes (USH1, USH2, and USH3) are inherited as recessive traits. People with Usher type 2 (USH2) have normal vestibular responses and moderate to severe hearing loss. These syndromes have been found to be genetically heterogeneous, with a single locus for USH2 at 1q...
متن کاملGenetic heterogeneity of Usher syndrome type II in a Dutch population.
The Usher syndromes are a group of autosomal recessive disorders characterised by retinitis pigmentosa (RP) with congenital, stable (non-progressive) sensorineural hearing loss. Profound deafness, RP, and no vestibular responses are features of Usher type I, whereas moderate to severe hearing loss and RP with normal vestibular function describe Usher type II. The gene responsible for most cases...
متن کاملAn Update on the Genetics of Usher Syndrome
Usher syndrome (USH) is an autosomal recessive disease characterized by hearing loss, retinitis pigmentosa (RP), and, in some cases, vestibular dysfunction. It is clinically and genetically heterogeneous and is the most common cause underlying deafness and blindness of genetic origin. Clinically, USH is divided into three types. Usher type I (USH1) is the most severe form and is characterized b...
متن کاملTwo Finnish USH1B patients with three novel mutations in myosin VIIA.
PURPOSE Usher syndrome (USH) is an autosomal recessive disorder resulting in retinal degeneration and sensorineural deafness caused by mutations in at least 10 gene loci. USH is divided into three main clinical types: USH1 (33-44%), USH2 (56-67%), and USH3. Worldwide, USH1 and USH2 account for most of the Usher syndrome cases with rare occurrence of USH3. In Finland, however, USH3 is the most c...
متن کاملThe usher syndromes.
Mutations in the gene (MYO7A) encoding myosin-VIIa, a member of the large superfamily of myosin motor proteins that move on cytoplasmic actin filaments, and in the USH2A gene, which encodes a novel protein resembling an extracellular matrix protein or a cell adhesion molecule, both cause Usher syndrome (USH), a clinically heterogeneous autosomal recessive disorder comprising hearing and visual ...
