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.

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 23, 2025This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 112 of the AP2S1 protein (p.Thr112Met). This variant is present in population databases (rs756038304, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with AP2S1-related conditions. ClinVar contains an entry for this variant (Variation ID: 2150903). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects AP2S1 function (PMID: 29325022). 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. -
