RCV001944770 | SCV002133017 | uncertain significance | not provided | 2021-05-08 | 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. This sequence change replaces arginine with glutamine at codon 1211 of the TUBGCP6 protein (p.Arg1211Gln). The arginine residue is moderately conserved and there is a small physicochemical difference between arginine and glutamine. This variant is present in population databases (rs370735400, ExAC 0.003%). This variant has not been reported in the literature in individuals with TUBGCP6-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. |
| Ambry Genetics | RCV002550989 | SCV003555655 | uncertain significance | Inborn genetic diseases | 2021-01-08 | criteria provided, single submitter | clinical testing | The c.3632G>A (p.R1211Q) alteration is located in exon 16 (coding exon 16) of the TUBGCP6 gene. This alteration results from a G to A substitution at nucleotide position 3632, causing the arginine (R) at amino acid position 1211 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
