RCV000768132 | SCV000899083 | uncertain significance | Cohen syndrome | 2021-03-30 | criteria provided, single submitter | clinical testing | VPS13B NM_017890 exon 29 p.His1443Gln (c.4329T>G): This variant has not been reported in the literature but is present in 2/33552 Latino alleles in the Genome Aggregation Database (http://gnomad.broadinstitute.org/rs201349007). Evolutionary conservation and computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. |

RCV000768132 | SCV000955169 | uncertain significance | Cohen syndrome | 2022-08-19 | criteria provided, single submitter | clinical testing | This sequence change replaces histidine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1443 of the VPS13B protein (p.His1443Gln). This variant is present in population databases (rs201349007, gnomAD 0.006%). This variant has not been reported in the literature in individuals affected with VPS13B-related conditions. ClinVar contains an entry for this variant (Variation ID: 626047). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available"). 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. |
Ambry Genetics | RCV002332546 | SCV002633268 | uncertain significance | Inborn genetic diseases | 2023-12-28 | criteria provided, single submitter | clinical testing | The c.4329T>G (p.H1443Q) alteration is located in exon 29 (coding exon 28) of the VPS13B gene. This alteration results from a T to G substitution at nucleotide position 4329, causing the histidine (H) at amino acid position 1443 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |

RCV003396333 | SCV004104485 | uncertain significance | VPS13B-related disorder | 2024-09-27 | no assertion criteria provided | clinical testing | The VPS13B c.4254T>G variant is predicted to result in the amino acid substitution p.His1418Gln. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0058% of alleles in individuals of Latino descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
