Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_006904.7(PRKDC):c.2629G>C(p.Asp877His) variant causes a missense change. The variant allele was found at a frequency of 0.0000532 in 1,521,864 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/19 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D877E) has been classified as Uncertain significance.

ClinVar
Submissions by phenotype
not specified Uncertain:1
The c.2629G>C (p.D877H) alteration is located in exon 24 (coding exon 24) of the PRKDC gene. This alteration results from a G to C substitution at nucleotide position 2629, causing the aspartic acid (D) at amino acid position 877 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Severe combined immunodeficiency due to DNA-PKcs deficiency Uncertain:1
This sequence change replaces aspartic acid, which is acidic and polar, with histidine, which is basic and polar, at codon 877 of the PRKDC protein (p.Asp877His). This variant is present in population databases (rs200560953, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with PRKDC-related conditions. ClinVar contains an entry for this variant (Variation ID: 475224). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt PRKDC protein function with a negative predictive value of 80%. 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. -
