Genes affected

ACTR3B (HGNC:17256): (actin related protein 3B) This gene encodes a member of the actin-related proteins (ARP), which form multiprotein complexes and share 35-55% amino acid identity with conventional actin. The protein encoded by this gene may have a regulatory role in the actin cytoskeleton and induce cell-shape change and motility. Pseudogenes of this gene are located on chromosomes 2, 4, 10, 16, 22 and Y. Alternative splicing results in multiple transcript variants and protein isoforms. [provided by RefSeq, Jul 2012]

The c.745C>T (p.P249S) alteration is located in exon 8 (coding exon 8) of the ACTR3B gene. This alteration results from a C to T substitution at nucleotide position 745, causing the proline (P) at amino acid position 249 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
