Genes affected

ARPIN (HGNC:28782): (actin related protein 2/3 complex inhibitor) Involved in directional locomotion; negative regulation of cell migration; and negative regulation of cellular component organization. Predicted to be located in lamellipodium. [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]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.615 is higher than 0.05.
