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.

NM_000448.3(RAG1):c.1064T>C is a missense variant predicted to cause substitution of Methionine by Threonine at amino acid 355 (p.Met355Thr).The highest population minor allele frequency in gnomAD v4 is 0.001815 (11/6062) in Middle Eastern population. (PM2_Supporting, BS1, and BA1 are not met). There are no publications for this variant in the literature. In summary, this variant meets the criteria to be classified as a variant of uncertain significance for autosomal recessive severe combined immunodeficiency due to RAG1 deficiency based on the ACMG/AMP criteria applied, as specified by the ClinGen SCID VCEP: No criteria met (VCEP specifications version 1). -

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). No publications were found based on this search. Allele frequency data from public databases did not allow this variant to be ruled in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. However, the evidence from the literature, in combination with allele frequency data from public databases where available, was not sufficient to rule this variant in or out of causing disease. Therefore, this variant is classified as a variant of unknown significance. -
