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]

The c.10687G>A (p.G3563R) alteration is located in exon 56 (coding exon 55) of the VPS13B gene. This alteration results from a G to A substitution at nucleotide position 10687, causing the glycine (G) at amino acid position 3563 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

The VPS13B c.10612G>A variant is predicted to result in the amino acid substitution p.Gly3538Arg. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.072% of alleles in individuals of African descent in gnomAD, which may be too common to be the primary cause of disease. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
