Genes affected

VPS45 (HGNC:14579): (vacuolar protein sorting 45 homolog) Vesicle mediated protein sorting plays an important role in segregation of intracellular molecules into distinct organelles. Genetic studies in yeast have identified more than 40 vacuolar protein sorting (VPS) genes involved in vesicle transport to vacuoles. This gene is a member of the Sec1 domain family, and shows a high degree of sequence similarity to mouse, rat and yeast Vps45. The exact function of this gene is not known, but its high expression in peripheral blood mononuclear cells suggests a role in trafficking proteins, including inflammatory mediators. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2013]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0018512905).
• BP6: Variant 1-150072183-T-G is Benign according to our data. Variant chr1-150072183-T-G is described in ClinVar as [Benign]. Clinvar id is 474244.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr1-150072183-T-G is described in Lovd as [Benign].
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.107 is higher than 0.05.
