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.

The c.88A>C (p.I30L) alteration is located in exon 2 (coding exon 2) of the AP2A2 gene. This alteration results from a A to C substitution at nucleotide position 88, causing the isoleucine (I) at amino acid position 30 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
