Genes affected
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]

Uncertain significance, no assertion criteria providedclinical testingDepartment of Pathology and Laboratory Medicine, Sinai Health System-The PLCE1 p.Ala643Ser variant was identified in the literature in 1 of 69 families with focal and segmental glomerulosclerosis (Gbadegesin_2009_PMID:18975016). The variant was identified in dbSNP (ID: rs61886330), ClinVar (classified as uncertain significance by Athena Diagnostics Inc) and LOVD 3.0 (classified as likely benign). The variant was identified in control databases in 383 of 280922 chromosomes (1 homozygous) at a frequency of 0.001363 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: European (Finnish) in 63 of 25038 chromosomes (freq: 0.002516), Other in 15 of 7146 chromosomes (freq: 0.002099), European (non-Finnish) in 270 of 128664 chromosomes (freq: 0.002098), South Asian in 16 of 30602 chromosomes (freq: 0.000523), Ashkenazi Jewish in 4 of 10360 chromosomes (freq: 0.000386), Latino in 13 of 35376 chromosomes (freq: 0.000368) and African in 2 of 24200 chromosomes (freq: 0.000083), but was not observed in the East Asian population. The p.Ala643 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -

Nephrotic syndrome, type 3 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaApr 27, 2017This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
