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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2024The c.1282G>C (p.V428L) alteration is located in exon 11 (coding exon 11) of the AP2A2 gene. This alteration results from a G to C substitution at nucleotide position 1282, causing the valine (V) at amino acid position 428 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
