NM_007259.5:c.712G>A
Variant summary
Our verdict is Pathogenic. Variant got 14 ACMG points: 14P and 0B. PM2PP3_StrongPP5_Very_Strong
The NM_007259.5(VPS45):c.712G>A(p.Glu238Lys) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000249 in 1,605,722 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. E238E) has been classified as Likely benign.

The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: <0.001%). Missense changes are a common disease-causing mechanism. In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.91; 3Cnet: 0.44). Same nucleotide change resulting in same amino acid change has been previously reported to be associated with VPS45-related disorder (ClinVar ID: VCV000055907 / PMID: 26358756). A different missense change at the same codon (p.Glu238Gln) has been reported to be associated with VPS45-related disorder (PMID: 23738510). Therefore, this variant is classified as Likely pathogenic according to the recommendation of ACMG/AMP guideline. -
This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 238 of the VPS45 protein (p.Glu238Lys). This variant is present in population databases (rs782269909, gnomAD 0.009%). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Experimental studies have shown that this missense change affects VPS45 function (PMID: 23738510). 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 VPS45 protein function. ClinVar contains an entry for this variant (Variation ID: 55907). This missense change has been observed in individuals with VPS45 deficiency (PMID: 23738510, 26358756, 32037586). -
