RCV001904092 | SCV002126082 | uncertain significance | not provided | 2022-10-15 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 536 of the TBX2 protein (p.Gly536Arg). This variant is present in population databases (rs760926920, gnomAD 0.5%). This variant has not been reported in the literature in individuals affected with TBX2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1358161). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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 | RCV004039642 | SCV003682283 | uncertain significance | not specified | 2022-02-17 | criteria provided, single submitter | clinical testing | The c.1606G>C (p.G536R) alteration is located in exon 6 (coding exon 6) of the TBX2 gene. This alteration results from a G to C substitution at nucleotide position 1606, causing the glycine (G) at amino acid position 536 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
