Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BA1BS2_Supporting

This summary comes from the ClinGen Evidence Repository: The NM_000448.3:c.251A>G variant in RAG1 is a missense variant predicted to cause the substitution of Histidine by Arginine at amino acid 249 (p.His84Arg). The Popmax Filtering allele frequency (95% CI) of the c.251A>G variant in RAG1 is 0.01622 in gnomAD v.4, which is higher than the ClinGen SCID VCEP threshold (>0.00872) for BA1. Therefore, BA1 is met. Additionally, 19 homozygous adults are reported on GnomAD v.4, BS2_Supporting is Met.In summary, this variant meets the criteria to be classified as Benign for autosomal recessive SCID. ACMG/AMP criteria applied, as specified by the ClinGen SCID-VCEP: BA1 and BS2_Supporting. (VCEP specifications version 1).

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.
