ClinGen Severe Combined Immunodeficiency Variant Curation Expert Panel, ClinGen	RCV000015964	SCV004242291	benign	Immunodeficiency 104	2024-01-23	reviewed by expert panel	curation	NM_002185.5(IL7R):c.197T>C is a missense variant predicted to cause substitution of Isoleucine by Threonine at amino acid 66 (p.Ile66Thr). The filtering allele frequency (the lower threshold of the 95% CI of 56371/74906 alleles) of the c.197T>C variant in IL7R is 0.7458 for African/African American chromosomes by gnomAD v.4, which is higher than the ClinGen SCID VCEP threshold (>0.00566) for BA1, and therefore meets this criterion (BA1). Additionally, 353136 homozygotes have been described. 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. Criteria applied: BA1 (VCEP specifications version 1).

Illumina Laboratory Services, Illumina	RCV000015964	SCV000457139	benign	Immunodeficiency 104	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.
Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	RCV000121212	SCV000539380	benign	not specified	2016-03-28	criteria provided, single submitter	clinical testing	Variant identified in a genome or exome case(s) and assessed due to predicted null impact of the variant or pathogenic assertions in the literature or databases. Disclaimer: This variant has not undergone full assessment. The following are preliminary notes: 1 paper published in 1998 claimed variant was pathogenic for SCID based on identification in 1 proband.
