Genes affected

ADGRA1 (HGNC:13838): (adhesion G protein-coupled receptor A1) This gene encodes a protein that belongs to the adhesion family of G-protein-coupled receptors. Members of this family function in several sensory systems and regulate blood pressure, immune responses, food intake and development. A similar protein in rodents is thought to play a role in in the regulation of neuronal signaling pathways. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined. [provided by RefSeq, Mar 2014]

The c.497C>T (p.A166V) alteration is located in exon 6 (coding exon 5) of the ADGRA1 gene. This alteration results from a C to T substitution at nucleotide position 497, causing the alanine (A) at amino acid position 166 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
