Genes affected

AP1G2 (HGNC:556): (adaptor related protein complex 1 subunit gamma 2) Adaptins are important components of clathrin-coated vesicles transporting ligand-receptor complexes from the plasma membrane or from the trans-Golgi network to lysosomes. The adaptin family of proteins is composed of four classes of molecules named alpha, beta-, beta prime- and gamma- adaptins. Adaptins, together with medium and small subunits, form a heterotetrameric complex called an adaptor, whose role is to promote the formation of clathrin-coated pits and vesicles. The protein encoded by this gene is a gamma-adaptin protein and it belongs to the adaptor complexes large subunits family. This protein along with the complex is thought to function at some trafficking step in the complex pathways between the trans-Golgi network and the cell surface. [provided by RefSeq, Aug 2017]

Ambry Genetics

Dec 27, 2023

The c.1714C>T (p.R572W) alteration is located in exon 17 (coding exon 16) of the AP1G2 gene. This alteration results from a C to T substitution at nucleotide position 1714, causing the arginine (R) at amino acid position 572 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
