Genes affected
AP3S2 (HGNC:571): (adaptor related protein complex 3 subunit sigma 2) Predicted to be involved in anterograde synaptic vesicle transport and vesicle-mediated transport. Located in intracellular membrane-bounded organelle. Part of AP-3 adaptor complex. [provided by Alliance of Genome Resources, Apr 2022]
ARPIN-AP3S2 (HGNC:38824): (ARPIN-AP3S2 readthrough) This locus represents naturally occurring read-through transcription between the neighboring C15orf38 (chromosome 15 open reading frame 38) and AP3S2 (adaptor-related protein complex 3, sigma 2 subunit) genes. The read-through transcript encodes a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Nov 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.206C>T (p.A69V) alteration is located in exon 3 (coding exon 3) of the AP3S2 gene. This alteration results from a C to T substitution at nucleotide position 206, causing the alanine (A) at amino acid position 69 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
