Genes affected

MMP14 (HGNC:7160): (matrix metallopeptidase 14) 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. However, the protein encoded by this gene is a member of the membrane-type MMP (MT-MMP) subfamily; each member of this subfamily contains a potential transmembrane domain suggesting that these proteins are expressed at the cell surface rather than secreted. This protein activates MMP2 protein, and this activity may be involved in tumor invasion. [provided by RefSeq, Jul 2008]

The c.73C>T (p.L25F) alteration is located in exon 1 (coding exon 1) of the MMP14 gene. This alteration results from a C to T substitution at nucleotide position 73, causing the leucine (L) at amino acid position 25 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces leucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 25 of the MMP14 protein (p.Leu25Phe). This variant is present in population databases (rs749088113, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with MMP14-related conditions. ClinVar contains an entry for this variant (Variation ID: 2528000). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
