Variant summary
Our verdict is Pathogenic. The variant received 12 ACMG points: 12P and 0B. PP3_StrongPP5_Very_Strong
The NM_006005.3(WFS1):c.2654C>T(p.Pro885Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000657 in 1,612,958 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 Likely pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. P885P) has been classified as Likely benign.

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 885 of the WFS1 protein (p.Pro885Leu). This variant is present in population databases (rs372855769, gnomAD 0.004%). This missense change has been observed in individuals with autosomal recessive Wolfram syndrome (PMID: 10521293, 28432734). ClinVar contains an entry for this variant (Variation ID: 437297). 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 expected to disrupt WFS1 protein function. Experimental studies have shown that this missense change affects WFS1 function (PMID: 16806192). For these reasons, this variant has been classified as Pathogenic. -

This variant has been previously reported as a heterozygous and homozygous change in patients with Wolfram-like Syndrome/ Wolfram Syndrome (PMID: 10521293, 30773290, 28432734). In vitro analysis illustrated that the c.2654C>T (p.Pro885Leu) variant results in reduce protein expression affecting WFS1 function (PMID: 16806192). The c.2654C>T (p.Pro885Leu) variant is present in the heterozygous state in the gnomAD population database at a frequency of 0.001% (3/249382) and thus is presumed to be rare. The c.2654C>T (p.Pro885Leu) variant affects a highly conserved amino acid and is predicted by multiple in silico tools to have a deleterious effect on protein function. Based on the available evidence, the c.2654C>T (p.Pro885Leu) variant is classified as Pathogenic. -
