Genes affected

AP1M2 (HGNC:558): (adaptor related protein complex 1 subunit mu 2) This gene encodes a subunit of the heterotetrameric adaptor-related protein comlex 1 (AP-1), which belongs to the adaptor complexes medium subunits family. This protein is capable of interacting with tyrosine-based sorting signals. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

Ambry Genetics

Nov 14, 2023

The c.445G>A (p.V149M) alteration is located in exon 5 (coding exon 5) of the AP1M2 gene. This alteration results from a G to A substitution at nucleotide position 445, causing the valine (V) at amino acid position 149 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
