Genes affected

MMP24 (HGNC:7172): (matrix metallopeptidase 24) This gene encodes a member of the peptidase M10 family 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. The encoded preproprotein is proteolytically processed to generate the mature protease. Unlike most MMPs, which are secreted, this protease is a member of the membrane-type MMP (MT-MMP) subfamily, contains a transmembrane domain and is expressed at the cell surface. Substrates of this protease include the proteins cadherin 2 and matrix metallopeptidase 2 (also known as 72 kDa type IV collagenase). The gene has previously been referred to as MMP25 but has been renamed matrix metallopeptidase 24 (MMP24). [provided by RefSeq, Oct 2019]

The c.38C>A (p.P13Q) alteration is located in exon (coding exon ) of the MMP24 gene. This alteration results from a C to A substitution at nucleotide position 38, causing the proline (P) at amino acid position 13 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
