| Invitae | RCV001064752 | SCV001229670 | uncertain significance | Severe combined immunodeficiency due to DNA-PKcs deficiency | 2020-02-22 | 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: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with PRKDC-related conditions. This variant is present in population databases (rs774703460, ExAC 0.01%). This sequence change replaces alanine with threonine at codon 751 of the PRKDC protein (p.Ala751Thr). The alanine residue is highly conserved and there is a small physicochemical difference between alanine and threonine. |
| Ambry Genetics | RCV002445334 | SCV002733446 | uncertain significance | Inborn genetic diseases | 2021-09-13 | criteria provided, single submitter | clinical testing | The p.A751T variant (also known as c.2251G>A), located in coding exon 20 of the PRKDC gene, results from a G to A substitution at nucleotide position 2251. The alanine at codon 751 is replaced by threonine, an amino acid with 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. |
