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.

Collection Method: clinical testing

The c.5C>G (p.P2R) alteration is located in exon 1 (coding exon 1) of the AP2A2 gene. This alteration results from a C to G substitution at nucleotide position 5, causing the proline (P) at amino acid position 2 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
