Submissions by phenotype

Epilepsy, familial focal, with variable foci 3 Uncertain:2
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpDec 27, 2023This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 415 of the NPRL3 protein (p.Ser415Pro). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with NPRL3-related conditions. ClinVar contains an entry for this variant (Variation ID: 476217). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt NPRL3 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. -
Uncertain significance, criteria provided, single submitterclinical testingBaylor GeneticsJul 31, 2018This variant was determined to be of uncertain significance according to ACMG Guidelines, 2015 [PMID:25741868]. -
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 30, 2023The c.1243T>C (p.S415P) alteration is located in exon 12 (coding exon 11) of the NPRL3 gene. This alteration results from a T to C substitution at nucleotide position 1243, causing the serine (S) at amino acid position 415 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
