Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BS2_Supporting BA1

This summary comes from the ClinGen Evidence Repository: The c.577G>A (NM_000448.3) variant in RAG1 is a missense variant predicted to cause the substitution of Glutamic Acid by Lysine at amino acid 193 (p.Glu193Lys).The filtering allele frequency (the lower threshold of the 95% CI of 772/30614) of the c.577G>A variant in RAG1 is 0.02374 for South Asian 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). 12 adult homozygous reported on GnomAD v2.1.1, BS2_Supporting is Met.In summary, this variant meets the criteria to be classified as Benign for autosomal recessive SCID based on the ACMG/AMP criteria applied, BA1 and BS2_Supporting, 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.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

Variant summary: RAG1 c.577G>A (p.Glu193Lys) results in a conservative amino acid change located in the RAG1 importin-binding domain of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0036 in 276652 control chromosomes, predominantly at a frequency of 0.025 within the South Asian subpopulation in the gnomAD database, including 10 homozygotes. The observed variant frequency within South Asian control individuals in the gnomAD database is approximately 35.36 fold of the estimated maximal expected allele frequency for a pathogenic variant in RAG1 causing Severe Combined Immunodeficiency Syndrome phenotype (0.00071), strongly suggesting that the variant is a benign polymorphism found primarily in populations of South Asian origin. To our knowledge, no occurrence of c.577G>A in individuals affected with Severe Combined Immunodeficiency Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. One clinical diagnostic laboratory has submitted clinical-significance assessments for this variant to ClinVar after 2014 without evidence for independent evaluation, classifying the variant as uncertain significance. Based on the evidence outlined above, the variant was classified as benign. -

The c.577G>A (NM_000448.3) variant in RAG1 is a missense variant predicted to cause the substitution of Glutamic Acid by Lysine at amino acid 193 (p.Glu193Lys). The filtering allele frequency (the lower threshold of the 95% CI of 772/30614) of the c.577G>A variant in RAG1 is 0.02374 for South Asian 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). 12 adult homozygous reported on GnomAD v2.1.1, BS2_Supporting is Met. In summary, this variant meets the criteria to be classified as Benign for autosomal recessive SCID based on the ACMG/AMP criteria applied, BA1 and BS2_Supporting, as specified by the ClinGen SCID VCEP (VCEP specifications version 1). -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This 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. -
