Genes affected

ADAMTS7 (HGNC:223): (ADAM metallopeptidase with thrombospondin type 1 motif 7) The protein encoded by this gene is a member of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) family. Members of this family share several distinct protein modules, including a propeptide region, a metalloproteinase domain, a disintegrin-like domain, and a thrombospondin type 1 (TS) motif. Individual members of this family differ in the number of C-terminal TS motifs, and some have unique C-terminal domains. The encoded preproprotein is proteolytically processed to generate the mature enzyme. This enzyme contains two C-terminal TS motifs and may regulate vascular smooth muscle cell (VSMC) migration. Mutations in this gene may be associated with susceptibility to coronary artery disease. [provided by RefSeq, Feb 2016]

The c.4948C>T (p.R1650C) alteration is located in exon 24 (coding exon 24) of the ADAMTS7 gene. This alteration results from a C to T substitution at nucleotide position 4948, causing the arginine (R) at amino acid position 1650 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
