Genes affected
COL6A5 (HGNC:26674): (collagen type VI alpha 5 chain) This gene encodes a member of the collagen superfamily of proteins. The encoded protein contains multiple von Willebrand factor A-like domains and may interact with the alpha 1 and alpha 2 chains of collagen VI to form the complete collagen VI trimer. Polymorphisms in this gene may be linked to dermal phenotypes, such as eczema. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2013]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2022The c.499G>A (p.V167M) alteration is located in exon 3 (coding exon 2) of the COL6A5 gene. This alteration results from a G to A substitution at nucleotide position 499, causing the valine (V) at amino acid position 167 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
