Genes affected

COL16A1 (HGNC:2193): (collagen type XVI alpha 1 chain) This gene encodes the alpha chain of type XVI collagen, a member of the FACIT collagen family (fibril-associated collagens with interrupted helices). Members of this collagen family are found in association with fibril-forming collagens such as type I and II, and serve to maintain the integrity of the extracellular matrix. High levels of type XVI collagen have been found in fibroblasts and keratinocytes, and in smooth muscle and amnion. [provided by RefSeq, Jul 2008]

The c.3947G>A (p.R1316Q) alteration is located in exon 64 (coding exon 63) of the COL16A1 gene. This alteration results from a G to A substitution at nucleotide position 3947, causing the arginine (R) at amino acid position 1316 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
