Variant summary
Our verdict is Uncertain significance. The variant received 3 ACMG points: 3P and 0B. PM1PP3
The NM_006005.3(WFS1):c.1538A>C(p.Tyr513Ser) variant causes a missense change. The variant allele was found at a frequency of 0.0000558 in 1,611,822 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 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. Y513C) has been classified as Uncertain significance.

Submissions by phenotype
not provided Uncertain:2
This sequence change replaces tyrosine, which is neutral and polar, with serine, which is neutral and polar, at codon 513 of the WFS1 protein (p.Tyr513Ser). This variant is present in population databases (rs544933961, gnomAD 0.01%). This missense change has been observed in individual(s) with WFS1-related conditions (PMID: 26284228, 31264968). ClinVar contains an entry for this variant (Variation ID: 215412). 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) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on WFS1 protein function. 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. -
Observed in heterozygous state in an infant with multiple congenital anomalies, bilateral hearing loss, developmental delay, and hypotonia who also had a missense variant in COL6A3 (Valencia et al., 2015); In silico analysis supports that this missense variant does not alter protein structure/function; Not observed at significant frequency in large population cohorts (Lek et al., 2016); This variant is associated with the following publications: (PMID: 31264968, 26284228, 27535533, 24464595) -
WFS1-Related Spectrum Disorders Uncertain:1
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). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
