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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2022The c.55C>T (p.R19C) alteration is located in exon 2 (coding exon 2) of the AP1M2 gene. This alteration results from a C to T substitution at nucleotide position 55, causing the arginine (R) at amino acid position 19 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
