Genes affected

NHEJ1 (HGNC:25737): (non-homologous end joining factor 1) Double-strand breaks in DNA result from genotoxic stresses and are among the most damaging of DNA lesions. This gene encodes a DNA repair factor essential for the nonhomologous end-joining pathway, which preferentially mediates repair of double-stranded breaks. Mutations in this gene cause different kinds of severe combined immunodeficiency disorders. [provided by RefSeq, Jul 2008]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.015193373).

BS1

Variant frequency is greater than expected in population amr. GnomAdExome4 allele frequency = 0.0000109 (16/1461276) while in subpopulation AMR AF = 0.000358 (16/44722). AF 95% confidence interval is 0.000224. There are 0 homozygotes in GnomAdExome4. There are 6 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 234 of the NHEJ1 protein (p.Gly234Ser). This variant is present in population databases (rs191958428, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with NHEJ1-related conditions. ClinVar contains an entry for this variant (Variation ID: 536738). 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 NHEJ1 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. -
