Genes affected

VWA2 (HGNC:24709): (von Willebrand factor A domain containing 2) This gene encodes a member of the von Willebrand factor A-like domain protein superfamily. The encoded protein is localized to the extracellular matrix and may serve as a structural component in basement membranes or in anchoring structures on scaffolds of collagen VII or fibrillin. This gene has been linked to type 1A diabetes and is a candidate serological marker for colon cancer. [provided by RefSeq, Jan 2013]

VWA2 links:

AFAP1L2 (HGNC:25901): (actin filament associated protein 1 like 2) Enables SH2 domain binding activity; SH3 domain binding activity; and protein tyrosine kinase activator activity. Involved in several processes, including positive regulation of epidermal growth factor receptor signaling pathway; regulation of gene expression; and regulation of mitotic cell cycle. Located in cytosol and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]
