Genes affected

CMA1 (HGNC:2097): (chymase 1) This gene encodes a chymotryptic serine proteinase that belongs to the peptidase family S1. It is expressed in mast cells and is thought to function in the degradation of the extracellular matrix, the regulation of submucosal gland secretion, and the generation of vasoactive peptides. In the heart and blood vessels, this protein, rather than angiotensin converting enzyme, is largely responsible for converting angiotensin I to the vasoactive peptide angiotensin II. Alternative splicing results in multiple variants. [provided by RefSeq, Apr 2015]

Collection Method: clinical testing

The c.509T>C (p.M170T) alteration is located in exon 4 (coding exon 4) of the CMA1 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. -
