Genes affected

ADAMTS12 (HGNC:14605): (ADAM metallopeptidase with thrombospondin type 1 motif 12) 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-1) motif. Individual members of this family differ in the number of C-terminal TS-1 motifs, and some have unique C-terminal domains. The enzyme encoded by this gene contains eight TS-1 motifs. It may play roles in pulmonary cells during fetal development or in tumor processes through its proteolytic activity or as a molecule potentially involved in regulation of cell adhesion.

The c.3985T>G (p.C1329G) alteration is located in exon 20 (coding exon 20) of the ADAMTS12 gene. This alteration results from a T to G substitution at nucleotide position 3985, causing the cysteine (C) at amino acid position 1329 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
