Genes affected
MMP19 (HGNC:7165): (matrix metallopeptidase 19) This gene encodes a member of a family of proteins that 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 protein is secreted as an inactive proprotein, which is activated upon cleavage by extracellular proteases. Alternative splicing results in multiple transcript variants for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 21, 2024The c.901C>T (p.R301C) alteration is located in exon 7 (coding exon 7) of the MMP19 gene. This alteration results from a C to T substitution at nucleotide position 901, causing the arginine (R) at amino acid position 301 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
