RCV001115785 | SCV001273793 | uncertain significance | Arthrogryposis, renal dysfunction, and cholestasis 1 | 2017-04-28 | criteria provided, single submitter | clinical testing | This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. |

RCV000598449 | SCV003462044 | uncertain significance | not provided | 2023-12-26 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 221 of the VPS33B protein (p.Arg221Gln). This variant is present in population databases (rs377754864, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with VPS33B-related conditions. ClinVar contains an entry for this variant (Variation ID: 502334). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt VPS33B protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |

RCV004754492 | SCV005346137 | uncertain significance | VPS33B-related disorder | 2024-07-11 | no assertion criteria provided | clinical testing | The VPS33B c.662G>A variant is predicted to result in the amino acid substitution p.Arg221Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0098% of alleles in individuals of South Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
