Genes affected
ACTR2 (HGNC:169): (actin related protein 2) The specific function of this gene has not yet been determined; however, the protein it encodes is known to be a major constituent of the ARP2/3 complex. This complex is located at the cell surface and is essential to cell shape and motility through lamellipodial actin assembly and protrusion. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.1041C>G (p.I347M) alteration is located in exon 10 (coding exon 10) of the ACTR2 gene. This alteration results from a C to G substitution at nucleotide position 1041, causing the isoleucine (I) at amino acid position 347 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
