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.

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 11, 2023This sequence change creates a premature translational stop signal (p.Arg108*) in the RAG1 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 936 amino acid(s) of the RAG1 protein. This variant is present in population databases (rs193922464, gnomAD 0.02%). This premature translational stop signal has been observed in individual(s) with severe combined immunodeficiency (PMID: 21664875, 24290284, 30290665). ClinVar contains an entry for this variant (Variation ID: 36714). Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this premature translational stop signal affects RAG1 function (PMID: 24290284). This variant disrupts a region of the RAG1 protein in which other variant(s) (p.Trp959*) have been determined to be pathogenic (PMID: 11133745, 24290284, 24406074). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. -
RAG1-related disorder Pathogenic:1
Pathogenic, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaDec 03, 2018The RAG1 c.322C>T (p.Arg108Ter) variant is a stop-gained variant that is predicted to result in a premature termination of the protein. The p.Arg108Ter variant has been reported in at least three studies in which it is found in a total of four individuals including in one in a homozygous state and three in a compound heterozygous state (Lee et al. 2014; Bai et al. 2016; Sharapova et al. 2016; Chi et al. 2018). Two of these individuals were described as having combined immune deficiency with one specifically diagnosed with Omenn syndrome. Control data are not available for the p.Arg108Ter variant which is reported at a frequency of 0.000159 in the East Asian population of the Genome Aggregation Database. Functional studies in cultured cells by Lee et al. (2014) demonstrated that the variant results in significantly reduced enzyme activity compared to wild type. Based on the potential impact of stop-gained variants and the supporting evidence from the literature, the p.Arg108Ter variant is classified as pathogenic for RAG1-related disorders. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -
