Variant summary
Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BS2
The NM_001077350.3(NPRL3):c.1313G>A(p.Ser438Asn) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000501 in 1,595,968 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S438R) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Feb 22, 2020 | 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. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with NPRL3-related disease. This variant is not present in population databases (ExAC no frequency). This sequence change replaces serine with asparagine at codon 438 of the NPRL3 protein (p.Ser438Asn). The serine residue is moderately conserved and there is a small physicochemical difference between serine and asparagine. - |
