Genes affected

MMP15 (HGNC:7161): (matrix metallopeptidase 15) This gene encodes a member of the peptidase M10 family and membrane-type subfamily of matrix metalloproteinases (MMPs). Proteins in this family are involved in the breakdown of extracellular matrix in normal physiological processes, such as embryonic development, reproduction, and tissue remodeling, as well as in disease processes, such as arthritis and metastasis. Members of this subfamily contain a transmembrane domain suggesting that these proteins are expressed at the cell surface rather than secreted. The encoded preproprotein is proteolytically processed to generate the mature protease. This protein may play a role in cancer progression. [provided by RefSeq, Jan 2016]

The c.376C>T (p.R126W) alteration is located in exon 3 (coding exon 3) of the MMP15 gene. This alteration results from a C to T substitution at nucleotide position 376, causing the arginine (R) at amino acid position 126 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
