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

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.77).
• BP6: Variant 1-12244229-T-G is Benign according to our data. Variant chr1-12244229-T-G is described in ClinVar as [Likely_benign]. Clinvar id is 1913123.Status of the report is criteria_provided_single_submitter, 1 stars.
