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

Jul 26, 2024

The c.836G>T (p.R279L) alteration is located in exon 8 (coding exon 8) of the AP2A2 gene. This alteration results from a G to T substitution at nucleotide position 836, causing the arginine (R) at amino acid position 279 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
