Variant summary

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

This summary comes from the ClinGen Evidence Repository: NM_002185.5(IL7R):c.412G>A is a missense variant predicted to cause substitution of Valine by Isoleucine at amino acid 138 (p.Val138Ile). The filtering allele frequency (the lower threshold of the 95% CI of 65661/74940 alleles) of the c.412G>A variant in IL7R is 0.8743 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, 367924 homozygous 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). LINK:https://erepo.genome.network/evrepo/ui/classification/CA124393/MONDO:0012163/119

Genes affected

IL7R (HGNC:6024): (interleukin 7 receptor) The protein encoded by this gene is a receptor for interleukin 7 (IL7). The function of this receptor requires the interleukin 2 receptor, gamma chain (IL2RG), which is a common gamma chain shared by the receptors of various cytokines, including interleukins 2, 4, 7, 9, and 15. This protein has been shown to play a critical role in V(D)J recombination during lymphocyte development. Defects in this gene may be associated with severe combined immunodeficiency (SCID). Alternatively spliced transcript variants have been found. [provided by RefSeq, Dec 2015]

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. -
