Genes affected

VPS13D (HGNC:23595): (vacuolar protein sorting 13 homolog D) This gene encodes a protein belonging to the vacuolar-protein-sorting-13 gene family. In yeast, vacuolar-protein-sorting-13 proteins are involved in trafficking of membrane proteins between the trans-Golgi network and the prevacuolar compartment. While several transcript variants may exist for this gene, the full-length natures of only two have been described to date. These two represent the major variants of this gene and encode distinct isoforms. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant where missense usually causes diseases, VPS13D

BP4

Computational evidence support a benign effect (MetaRNN=0.042104244).

BS1

Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000192 (28/1461864) while in subpopulation AMR AF= 0.000604 (27/44722). AF 95% confidence interval is 0.000425. There are 0 homozygotes in gnomad4_exome. There are 9 alleles in male gnomad4_exome subpopulation. Median coverage is 31. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

This sequence change replaces serine, which is neutral and polar, with arginine, which is basic and polar, at codon 84 of the VPS13D protein (p.Ser84Arg). This variant is present in population databases (rs747997002, gnomAD 0.07%). This variant has not been reported in the literature in individuals affected with VPS13D-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
