Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 3P and 4B. PM2PP2BP4_Strong

The NM_000448.3(RAG1):​c.830A>G​(p.Lys277Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000723 in 152,230 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. K277K) has been classified as Likely benign.

Genes affected
RAG1 (HGNC:9831): (recombination activating 1) The protein encoded by this gene is involved in activation of immunoglobulin V-D-J recombination. The encoded protein is involved in recognition of the DNA substrate, but stable binding and cleavage activity also requires RAG2. Defects in this gene can be the cause of several diseases.

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 59 curated pathogenic missense variants (we use a threshold of 10). The gene has 19 curated benign missense variants. Gene score misZ: 0.5811 (below the threshold of 3.09). Trascript score misZ: 1.7677 (below the threshold of 3.09). GenCC associations: The gene is linked to combined immunodeficiency due to partial RAG1 deficiency, severe combined immunodeficiency, autosomal recessive, T cell-negative, B cell-negative, NK cell-positive, Omenn syndrome, recombinase activating gene 1 deficiency, immunodeficiency disease.
BP4
Computational evidence support a benign effect (MetaRNN=0.027899921).
