Genes affected

AP2S1 (HGNC:565): (adaptor related protein complex 2 subunit sigma 1) One of two major clathrin-associated adaptor complexes, AP-2, is a heterotetramer which is associated with the plasma membrane. This complex is composed of two large chains, a medium chain, and a small chain. This gene encodes the small chain of this complex. Alternative splicing results in multiple transcript variants.
