RCV001897440 | SCV002149420 | uncertain significance | Charcot-Marie-Tooth disease type 2 | 2021-02-12 | criteria provided, single submitter | clinical testing | 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. 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: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with KIF1B-related conditions. This variant is present in population databases (rs762619916, ExAC 0.001%). This sequence change replaces proline with leucine at codon 916 of the KIF1B protein (p.Pro916Leu). The proline residue is highly conserved and there is a moderate physicochemical difference between proline and leucine. |
| Ambry Genetics | RCV004041254 | SCV005026618 | uncertain significance | not specified | 2024-02-06 | criteria provided, single submitter | clinical testing | The p.P916L variant (also known as c.2747C>T), located in coding exon 24 of the KIF1B gene, results from a C to T substitution at nucleotide position 2747. The proline at codon 916 is replaced by leucine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this alteration remains unclear. |
