Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_152564.5(VPS13B):c.9349A>G(p.Ser3117Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00768 in 1,382,896 control chromosomes in the GnomAD database, including 104 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S3117N) has been classified as Uncertain significance.

Genes affected

VPS13B (HGNC:2183): (vacuolar protein sorting 13 homolog B) This gene encodes a potential transmembrane protein that may function in vesicle-mediated transport and sorting of proteins within the cell. This protein may play a role in the development and the function of the eye, hematological system, and central nervous system. Mutations in this gene have been associated with Cohen syndrome. Multiple splice variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0035758317).

BP6

Variant 8-99832387-A-G is Benign according to our data. Variant chr8-99832387-A-G is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 95874.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00689 (694/100794) while in subpopulation SAS AF = 0.0257 (91/3534). AF 95% confidence interval is 0.0215. There are 6 homozygotes in GnomAd4. There are 358 alleles in the male GnomAd4 subpopulation. Median coverage is 21. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 6 AR gene
