Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_001030059.3(PLPP4):​c.45C>G​(p.Phe15Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: not found (cov: 33)
• Consequence: PLPP4 NM_001030059.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.0300

Genes affected

PLPP4 (HGNC:23531): (phospholipid phosphatase 4) Enables diacylglycerol diphosphate phosphatase activity; identical protein binding activity; and phosphatidate phosphatase activity. Involved in phospholipid dephosphorylation and regulation of calcium ion import. Predicted to be located in plasma membrane. Biomarker of breast cancer. [provided by Alliance of Genome Resources, Apr 2022]
