Genes affected

AP2A2 (HGNC:562): (adaptor related protein complex 2 subunit alpha 2) The protein encoded by this gene is a subunit of the AP-2 adaptor protein complex, which is involved in linking lipid and protein membrane components with the clathrin lattice. This interaction supports the formation of clathrin-coated vesicles, and the encoded subunit aids in the process by binding polyphosphoinositide-containing lipids in the cell membrane.

Ambry Genetics

Nov 12, 2021

The c.676G>A (p.V226M) alteration is located in exon 6 (coding exon 6) of the AP2A2 gene. This alteration results from a G to A substitution at nucleotide position 676, causing the valine (V) at amino acid position 226 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
