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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.57C>A (p.F19L) alteration is located in exon 2 (coding exon 1) of the ARPC2 gene. This alteration results from a C to A substitution at nucleotide position 57, causing the phenylalanine (F) at amino acid position 19 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
