Genes affected
PPP1R15A (HGNC:14375): (protein phosphatase 1 regulatory subunit 15A) This gene is a member of a group of genes whose transcript levels are increased following stressful growth arrest conditions and treatment with DNA-damaging agents. The induction of this gene by ionizing radiation occurs in certain cell lines regardless of p53 status, and its protein response is correlated with apoptosis following ionizing radiation.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 30, 2023The c.166G>A (p.V56I) alteration is located in exon 2 (coding exon 1) of the PPP1R15A gene. This alteration results from a G to A substitution at nucleotide position 166, causing the valine (V) at amino acid position 56 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
