Variant summary

Our verdict is Benign. Variant got -8 ACMG points: 0P and 8B. BA1

This summary comes from the ClinGen Evidence Repository: The c.906C>A (NM_000448.3) variant in RAG1 is a missense variant predicted to cause substitution of Aspartic Acid by Glutamic Acid at amino acid 302 (p.Asp302Glu).The filtering allele frequency (the lower threshold of the 95% CI of 1968/24958) of the c.906C>A variant in RAG1 is 0.07684 for African/African American chromosomes by gnomAD v2.1.1, which is higher than the ClinGen SCID VCEP threshold (>0.00872) for BA1, and therefore meets this criterion (BA1).In summary, this variant meets the criteria to be classified as Benign for autosomal recessive SCID based on the ACMG/AMP criteria applied, BA1, as specified by the ClinGen SCID VCEP (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.

Benign, criteria provided, single submitterclinical testingGeneDxDec 18, 2013This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Benign, reviewed by expert panelcurationClinGen Severe Combined Immunodeficiency Variant Curation Expert Panel, ClinGenNov 14, 2023The c.906C>A (NM_000448.3) variant in RAG1 is a missense variant predicted to cause substitution of Aspartic Acid by Glutamic Acid at amino acid 302 (p.Asp302Glu). The filtering allele frequency (the lower threshold of the 95% CI of 1968/24958) of the c.906C>A variant in RAG1 is 0.07684 for African/African American chromosomes by gnomAD v2.1.1, which is higher than the ClinGen SCID VCEP threshold (>0.00872) for BA1, and therefore meets this criterion (BA1). In summary, this variant meets the criteria to be classified as Benign for autosomal recessive SCID based on the ACMG/AMP criteria applied, BA1, as specified by the ClinGen SCID VCEP (VCEP specifications version 1). -

Benign, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaJan 12, 2018This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
