Genes affected

ADAMTS6 (HGNC:222): (ADAM metallopeptidase with thrombospondin type 1 motif 6) This gene encodes a member of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) 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. Expression of this gene may be regulated by the cytokine TNF-alpha. [provided by RefSeq, Mar 2016]

The c.2302A>G (p.I768V) alteration is located in exon 19 (coding exon 18) of the ADAMTS6 gene. This alteration results from a A to G substitution at nucleotide position 2302, causing the isoleucine (I) at amino acid position 768 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
