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=0.009522557).

BS1

Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.0000656 (10/152340) while in subpopulation EAS AF = 0.00135 (7/5186). AF 95% confidence interval is 0.000633. There are 0 homozygotes in GnomAd4. There are 4 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
