usher syndromes/seizures

The human ortholog of the gene responsible for audiogenic seizure susceptibility in Frings and BUB/BnJ mice (mouse gene symbol Mass1) recently was shown to underlie Usher syndrome type IIC (USH2C). Here we report that the Mass1frings mutation is responsible for the early onset hearing impairment of

We report on a 1-year-old boy with microcephaly with a simplified gyral pattern, early-onset seizures, congenital hearing loss and a severe developmental delay. Trio-based whole-exome sequencing identified candidate compound heterozygous mutations in two genes: c.163G>T (p.Ala55Ser) and c.874G>A

Usher syndrome type II (USH2) is a genetically heterogeneous autosomal recessive disorder with at least three genetic subtypes (USH2A, USH2B, and USH2C) and is classified phenotypically as congenital hearing loss and progressive retinitis pigmentosa. The VLGR1 (MASS1) gene in the 5q14.3-q21.1 USH2C

An 18-year-old female with mild mental disability (global IQ 69), febrile seizures with subsequent myoclonic/grand mal epilepsy, and subtle morphologic changes is described with del 5(q14.3q21.3) by karyotype and minimal DNA deletion of 21.08 Mb by array comparative genomic hybridization microarray

The very large G protein-coupled receptor 1 (VLGRI), also known as MASS1 or GPR98, is most notable among the family of adhesion-GPCR for its size. Encoded by an 18.9 kb open reading frame, the approximately 700 kDa primary translation product is by far the largest GPCR and additionally, the largest

The very large G protein coupled receptor (Vlgr1) is a member of adhesion receptors or large N-terminal family B-7 transmembrane helixes (LNB7TM) receptors within the seven trans-membrane receptor superfamily. Vlgr1 is the largest GPCR identified to date; its mRNA spans 19 kb and encodes 6,300 amino
