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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This 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. -

The PLCE1 p.Ala643Thr variant was not identified in the literature nor was it identified in ClinVar. The variant was identified in dbSNP (ID: rs61886330) and in control databases in 89 of 280922 chromosomes at a frequency of 0.0003168 (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: Latino in 18 of 35376 chromosomes (freq: 0.000509), European (non-Finnish) in 58 of 128664 chromosomes (freq: 0.000451), African in 5 of 24200 chromosomes (freq: 0.000207), South Asian in 6 of 30602 chromosomes (freq: 0.000196), East Asian in 1 of 19536 chromosomes (freq: 0.000051) and European (Finnish) in 1 of 25038 chromosomes (freq: 0.00004), but was not observed in the Ashkenazi Jewish, or Other populations. 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 643 of the PLCE1 protein (p.Ala643Thr). This variant is present in population databases (rs61886330, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with PLCE1-related conditions. ClinVar contains an entry for this variant (Variation ID: 879317). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt PLCE1 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
