Inborn genetic diseases Uncertain:1
The p.R202Q variant (also known as c.605G>A), located in coding exon 6 of the BUB1B gene, results from a G to A substitution at nucleotide position 605. The arginine at codon 202 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
Mosaic variegated aneuploidy syndrome 1 Uncertain:1
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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 403755). This variant has not been reported in the literature in individuals affected with BUB1B-related conditions. This variant is present in population databases (rs768417752, gnomAD 0.007%). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 202 of the BUB1B protein (p.Arg202Gln). -
