Our verdict is Benign. Variant got -8 ACMG points: 2P and 10B. PM2BP4_StrongBP6_ModerateBS1
The NM_016341.4(PLCE1):c.4795+8A>G variant causes a splice region, intron change. The variant allele was found at a frequency of 0.0000663 in 1,613,468 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 1/1 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Likely benign (★).
PLCE1 (HGNC:17175): (phospholipase C epsilon 1) This gene encodes a phospholipase enzyme that catalyzes the hydrolysis of phosphatidylinositol-4,5-bisphosphate to generate two second messengers: inositol 1,4,5-triphosphate (IP3) and diacylglycerol (DAG). These second messengers subsequently regulate various processes affecting cell growth, differentiation, and gene expression. This enzyme is regulated by small monomeric GTPases of the Ras and Rho families and by heterotrimeric G proteins. In addition to its phospholipase C catalytic activity, this enzyme has an N-terminal domain with guanine nucleotide exchange (GEF) activity. Mutations in this gene cause early-onset nephrotic syndrome; characterized by proteinuria, edema, and diffuse mesangial sclerosis or focal and segmental glomerulosclerosis. Alternative splicing results in multiple transcript variants encoding distinct isoforms.[provided by RefSeq, Sep 2009]

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.64).
BP6
Variant 10-94279919-A-G is Benign according to our data. Variant chr10-94279919-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 3031934.Status of the report is criteria_provided_single_submitter, 1 stars.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000341 (52/152288) while in subpopulation AFR AF= 0.00118 (49/41556). AF 95% confidence interval is 0.000915. There are 1 homozygotes in gnomad4. There are 28 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
This variant is classified as likely benign based on ACMG/AMP sequence variant interpretation guidelines (Richards et al. 2015 PMID: 25741868, with internal and published modifications). -
