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.

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with AP2S1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.002%). This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 122 of the AP2S1 protein (p.Glu122Lys). -
