Genes affected

MAS1 (HGNC:6899): (MAS1 proto-oncogene, G protein-coupled receptor) This gene encodes a class I seven-transmembrane G-protein-coupled receptor. The encoded protein is a receptor for angiotensin-(1-7) and preferentially couples to the Gq protein, activating the phospholipase C signaling pathway. The encoded protein may play a role in multiple processes including hypotension, smooth muscle relaxation and cardioprotection by mediating the effects of angiotensin-(1-7).

Collection Method: clinical testing

The c.509T>C (p.M170T) alteration is located in exon 1 (coding exon 1) of the MAS1 gene. This alteration results from a T to C substitution at nucleotide position 509, causing the methionine (M) at amino acid position 170 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
