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 was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000276 (42/152148) while in subpopulation NFE AF = 0.000573 (39/68016). AF 95% confidence interval is 0.000431. There are 0 homozygotes in GnomAd4. There are 23 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 3267 of the VPS13D protein (p.Arg3267Trp). This variant is present in population databases (rs140427465, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with VPS13D-related conditions. ClinVar contains an entry for this variant (Variation ID: 560297). 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 VPS13D 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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing;provider interpretation

This 5 year old male with autism spectrum disorder, developmental delays, and a bifid uvula was found to be compound heterozygote for two missense variants in the VPS13D gene (p.Y2812H/p.R3267W). At the time of report, the VPS13D gene had no clear association with human disease, although a de novo variant has been reported in a single individual with schizophrenia (McCarthy, 2014). The p.Arg3267Trp variant is present at 0.02% in the gnomAD dataset. Computational models predict the variant to be damaging.
