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

Jan 20, 2023

The c.893A>G (p.K298R) alteration is located in exon 8 (coding exon 8) of the AP2A2 gene. This alteration results from a A to G substitution at nucleotide position 893, causing the lysine (K) at amino acid position 298 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
