Genetic Variant NM_152862.3:c.842G>A (chr2-218249885-G-A) – ACMG Classification: Likely_benign (-4 pts)

Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 1P and 5B. PP3BP4BS2

The NM_152862.3(ARPC2):c.842G>A(p.Arg281His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000039 in 1,613,514 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R281C) has been classified as Uncertain significance.

Genes affected

ARPC2 (HGNC:705): (actin related protein 2/3 complex subunit 2) This gene encodes one of seven subunits of the human Arp2/3 protein complex. The Arp2/3 protein complex has been implicated in the control of actin polymerization in cells and has been conserved through evolution. The exact role of the protein encoded by this gene, the p34 subunit, has yet to be determined. Two alternatively spliced variants have been characterized to date. Additional alternatively spliced variants have been described but their full length nature has not been determined. [provided by RefSeq, Jul 2008]
