Genes affected

COL6A6 (HGNC:27023): (collagen type VI alpha 6 chain) This gene encodes a large protein that contains multiple von Willebrand factor domains and forms a component of the basal lamina of epithelial cells. This protein may regulate epithelial cell-fibronectin interactions. Variation in this gene may be implicated in skin diseases. [provided by RefSeq, May 2017]
