Variant summary

Our verdict is Benign. The variant received -10 ACMG points: 0P and 10B. BP7BS2_SupportingBA1

This summary comes from the ClinGen Evidence Repository: The c.303G>A (p.Ala101=) variant (NM_000022.4) is a synonymous (silent) variant that is not predicted by SpliceAI and varSEAK to impact splicing (BP7).The filtering allele frequency (the lower threshold of the 95% CI of 799/30614) of the c.303G>A variant in RAG1 is 0.02460 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). Additionally, 76 homozygous individuals were reported (BS2_Supporting is met). In summary, this variant is classified as a Benign for autosomal recessive SCID based on ACMG/AMP criteria applied, as specified by the ClinGen SCID VCEP (specification version 1.0): BA1, BS2_Supporting, and BP7.

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.

Significance:Benign
Review Status:reviewed by expert panel
Collection Method:curation

The c.303G>A (p.Ala101=) variant (NM_000022.4) is a synonymous (silent) variant that is not predicted by SpliceAI and varSEAK to impact splicing (BP7). The filtering allele frequency (the lower threshold of the 95% CI of 799/30614) of the c.303G>A variant in RAG1 is 0.02460 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). Additionally, 76 homozygous individuals were reported (BS2_Supporting is met). In summary, this variant is classified as a Benign for autosomal recessive SCID based on ACMG/AMP criteria applied, as specified by the ClinGen SCID VCEP (specification version 1.0): BA1, BS2_Supporting, and BP7. -

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. -
