Genes affected

PPP1R10 (HGNC:9284): (protein phosphatase 1 regulatory subunit 10) This gene encodes a protein phosphatase 1 binding protein. The encoded protein plays a role in many cellular processes including cell cycle progression, DNA repair and apoptosis by regulating the activity of protein phosphatase 1. This gene lies within the major histocompatibility complex class I region on chromosome 6, and alternatively spliced transcript variants have been observed for this gene.

The c.2314G>C (p.G772R) alteration is located in exon 19 (coding exon 17) of the PPP1R10 gene. This alteration results from a G to C substitution at nucleotide position 2314, causing the glycine (G) at amino acid position 772 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
