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 Likely_benign. Variant got -6 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.37).
BP6
Variant 20-8790186-G-A is Benign according to our data. Variant chr20-8790186-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 129897.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=2}.
BP7
Synonymous conserved (PhyloP=0.303 with no splicing effect.
BS1
Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0000439 (64/1457210) while in subpopulation MID AF= 0.000174 (1/5762). AF 95% confidence interval is 0.0000381. There are 0 homozygotes in gnomad4_exome. There are 37 alleles in male gnomad4_exome subpopulation. Median coverage is 30. This position pass quality control queck.
