Genes affected

ACTR3 (HGNC:170): (actin related protein 3) 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. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Mar 2013]

The c.908T>C (p.V303A) alteration is located in exon 9 (coding exon 9) of the ACTR3 gene. This alteration results from a T to C substitution at nucleotide position 908, causing the valine (V) at amino acid position 303 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
