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]

Benign, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpSep 18, 2017Variant summary: c.6530-4dupT in VPS13B gene is an intronic change that involves a non-conserved nucleotide. 5/5 programs in Alamut predict that this variant does not affect a normal splicing, however no functional studies supporting this notion were published at the time of evaluation. The variant is present in the control population dataset of ExAC at frequency of 0.01956 (1930/98690 chrs tested, including 49 homozygotes), predominantly in individuals of South Asian descent (0.068; 1002/14612 chrs tested). The observed frequency greatly exceeds the maximum expected allele frequency for a pathogenic variant of 0.0025, suggesting that it is likely to be a common polymorphism. The variant of interest has not, to our knowledge, been reported in affected individuals in published reports but is cited as Likely Benign/Benign by reputable database/clinical laboratory. Taking together, the variant was classified as Benign. -

Benign, criteria provided, single submitterclinical testingAmbry GeneticsMay 15, 2017This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
