Genes affected

PHACTR3 (HGNC:15833): (phosphatase and actin regulator 3) This gene encodes a member of the phosphatase and actin regulator protein family. The encoded protein is associated with the nuclear scaffold in proliferating cells, and binds to actin and the catalytic subunit of protein phosphatase-1, suggesting that it functions as a regulatory subunit of protein phosphatase-1. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

The c.475G>C (p.A159P) alteration is located in exon 4 (coding exon 4) of the PHACTR3 gene. This alteration results from a G to C substitution at nucleotide position 475, causing the alanine (A) at amino acid position 159 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
