Genes affected

PLCB1 (HGNC:15917): (phospholipase C beta 1) The protein encoded by this gene catalyzes the formation of inositol 1,4,5-trisphosphate and diacylglycerol from phosphatidylinositol 4,5-bisphosphate. This reaction uses calcium as a cofactor and plays an important role in the intracellular transduction of many extracellular signals. This gene is activated by two G-protein alpha subunits, alpha-q and alpha-11. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), PLCB1. . Gene score misZ 3.8345 (greater than the threshold 3.09). Trascript score misZ 3.6982 (greater than threshold 3.09). GenCC has associacion of gene with developmental and epileptic encephalopathy, 12, malignant migrating partial seizures of infancy, developmental and epileptic encephalopathy, West syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.26174375).
