Genes affected

COL15A1 (HGNC:2192): (collagen type XV alpha 1 chain) This gene encodes the alpha chain of type XV collagen, a member of the FACIT collagen family (fibril-associated collagens with interrupted helices). Type XV collagen has a wide tissue distribution but the strongest expression is localized to basement membrane zones so it may function to adhere basement membranes to underlying connective tissue stroma. The proteolytically produced C-terminal fragment of type XV collagen is restin, a potentially antiangiogenic protein that is closely related to endostatin. Mouse studies have shown that collagen XV deficiency is associated with muscle and microvessel deterioration. [provided by RefSeq, May 2013]

The c.466G>T (p.V156L) alteration is located in exon 3 (coding exon 3) of the COL15A1 gene. This alteration results from a G to T substitution at nucleotide position 466, causing the valine (V) at amino acid position 156 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
