Genes affected

MMP27 (HGNC:14250): (matrix metallopeptidase 27) 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. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.1231C>T (p.P411S) alteration is located in exon 9 (coding exon 9) of the MMP27 gene. This alteration results from a C to T substitution at nucleotide position 1231, causing the proline (P) at amino acid position 411 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
