Genes affected
PHLPP1 (HGNC:20610): (PH domain and leucine rich repeat protein phosphatase 1) This gene encodes a member of the serine/threonine phosphatase family. The encoded protein promotes apoptosis by dephosphorylating and inactivating the serine/threonine kinase Akt, and functions as a tumor suppressor in multiple types of cancer. Increased expression of this gene may also play a role in obesity and type 2 diabetes by interfering with Akt-mediated insulin signaling. [provided by RefSeq, Dec 2011]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 14, 2023The c.520A>T (p.R174W) alteration is located in exon 1 (coding exon 1) of the PHLPP1 gene. This alteration results from a A to T substitution at nucleotide position 520, causing the arginine (R) at amino acid position 174 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
