Genes affected
PLCB4 (HGNC:9059): (phospholipase C beta 4) 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 in the retina. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2010]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.14850962).
BS1
Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.0000192 (28/1461100) while in subpopulation EAS AF = 0.000681 (27/39668). AF 95% confidence interval is 0.00048. There are 0 homozygotes in GnomAdExome4. There are 15 alleles in the male GnomAdExome4 subpopulation. Median coverage is 29. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
