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

Our verdict: Benign. The variant received -17 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.5).
• BP6: Variant 1-12242520-T-C is Benign according to our data. Variant chr1-12242520-T-C is described in ClinVar as Likely_benign. ClinVar VariationId is 2155278.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=1.42 with no splicing effect.
• BS1: Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.000091 (133/1461654) while in subpopulation SAS AF = 0.000696 (60/86246). AF 95% confidence interval is 0.000554. There are 1 homozygotes in GnomAdExome4. There are 72 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check.
