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]

Sep 17, 2021

The c.775G>A (p.A259T) alteration is located in exon 7 (coding exon 6) of the ADGRA1 gene. This alteration results from a G to A substitution at nucleotide position 775, causing the alanine (A) at amino acid position 259 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
