Genes affected

ADGRV1 (HGNC:17416): (adhesion G protein-coupled receptor V1) This gene encodes a member of the G-protein coupled receptor superfamily. The encoded protein contains a 7-transmembrane receptor domain, binds calcium and is expressed in the central nervous system. Mutations in this gene are associated with Usher syndrome 2 and familial febrile seizures. Several alternatively spliced transcripts have been described. [provided by RefSeq, Jul 2008]

LUCAT1 (HGNC:48498): (lung cancer associated transcript 1)
