Genes affected

MMP16 (HGNC:7162): (matrix metallopeptidase 16) Proteins of the matrix metalloproteinase (MMP) 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. Most MMP's are secreted as inactive proproteins which are activated when cleaved by extracellular proteinases. The encoded protein activates MMP2 by cleavage. This gene was once referred to as MT-MMP2, but was renamed as MT-MMP3 or MMP16. [provided by RefSeq, Oct 2010]

The c.239A>G (p.Y80C) alteration is located in exon 2 (coding exon 2) of the MMP16 gene. This alteration results from a A to G substitution at nucleotide position 239, causing the tyrosine (Y) at amino acid position 80 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
