Genes affected

ADAMTS14 (HGNC:14899): (ADAM metallopeptidase with thrombospondin type 1 motif 14) This gene encodes a member of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motif) protein family. Members of the 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 cleaves amino-terminal propeptides from type I procollagen, a necessary step in the formation of collagen fibers. Mutations in this gene may be associated with osteoarthritis in human patients. [provided by RefSeq, May 2016]

Collection Method: clinical testing

The c.250C>T (p.R84W) alteration is located in exon 2 (coding exon 2) of the ADAMTS14 gene. This alteration results from a C to T substitution at nucleotide position 250, causing the arginine (R) at amino acid position 84 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
