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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 06, 2024The c.769C>T (p.R257C) alteration is located in exon 7 (coding exon 6) of the ADGRA1 gene. This alteration results from a C to T substitution at nucleotide position 769, causing the arginine (R) at amino acid position 257 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
