The ENST00000570308.5(MMP2):c.-75-5015C>T variant causes a intron change involving the alteration of a non-conserved nucleotide. Note: ENST00000570308.5 is not a MANE Select or MANE Plus Clinical transcript for MMP2; the reported annotation may differ from that of the MANE-designated reference transcript for this gene. The variant allele was found at a cumulative frequency of 0.187 (AC=28,505) in the gnomAD database across 152,156 control chromosomes, including 3,255 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.246. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Variant has been reported in ClinVar as Uncertain Significance (★).

Genes affected

MMP2 (HGNC:7166): (matrix metallopeptidase 2) This gene is a member of the matrix metalloproteinase (MMP) gene family, that are zinc-dependent enzymes capable of cleaving components of the extracellular matrix and molecules involved in signal transduction. The protein encoded by this gene is a gelatinase A, type IV collagenase, that contains three fibronectin type II repeats in its catalytic site that allow binding of denatured type IV and V collagen and elastin. Unlike most MMP family members, activation of this protein can occur on the cell membrane. This enzyme can be activated extracellularly by proteases, or, intracellulary by its S-glutathiolation with no requirement for proteolytical removal of the pro-domain. This protein is thought to be involved in multiple pathways including roles in the nervous system, endometrial menstrual breakdown, regulation of vascularization, and metastasis. Mutations in this gene have been associated with Winchester syndrome and Nodulosis-Arthropathy-Osteolysis (NAO) syndrome. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Oct 2014]
