ClinGen Severe Combined Immunodeficiency Variant Curation Expert Panel, ClinGen	RCV003492577	SCV004242266	benign	Recombinase activating gene 1 deficiency	2024-01-23	reviewed by expert panel	curation	The NM_000448.3:c.2638G>A variant in RAG1 is a missense variant predicted to cause the substitution of Glutamic Acid by Lysine at amino acid 880 (p.Glu880Lys). The filtering allele frequency (the lower threshold of the 95% CI of 3496/75044) of the c.2638G>A variant in RAG1 is 0.04730 for African/African American chromosomes by gnomAD v.4, which is higher than the ClinGen SCID VCEP threshold (>0.00872) for BA1, and therefore meets this criterion (BA1). Additionally, 84 homozygous adults are reported on gnomAD v.4 (BS2_Supporting). In summary, this variant meets the criteria to be classified as Benign for autosomal recessive SCID based on the ACMG/AMP criteria applied, as specified by the ClinGen SCID-VCEP: BA1 and BS2_Supporting. (VCEP specifications version 1).
GeneDx	RCV000127711	SCV000171290	benign	not specified	2014-02-28	criteria provided, single submitter	clinical testing	This 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.

Illumina Laboratory Services, Illumina	RCV001105407	SCV001262367	benign	Histiocytic medullary reticulosis	2018-01-12	criteria provided, single submitter	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.
