Genes affected

AP3M1 (HGNC:569): (adaptor related protein complex 3 subunit mu 1) The protein encoded by this gene is the medium subunit of AP-3, which is an adaptor-related protein complex associated with the Golgi region as well as more peripheral intracellular structures. AP-3 facilitates the budding of vesicles from the Golgi membrane, and it may directly function in protein sorting to the endosomal/lysosomal system. AP-3 is a heterotetrameric protein complex composed of two large subunits (delta and beta3), a medium subunit (mu3), and a small subunit (sigma 3). Mutations in one of the large subunits of AP-3 have been associated with the Hermansky-Pudlak syndrome, a genetic disorder characterized by defective lysosome-related organelles. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Feb 2016]

Ambry Genetics

Apr 12, 2024

The c.182G>A (p.R61Q) alteration is located in exon 3 (coding exon 1) of the AP3M1 gene. This alteration results from a G to A substitution at nucleotide position 182, causing the arginine (R) at amino acid position 61 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
