Variant summary

Our verdict is Benign. Variant got -9 ACMG points: 0P and 9B. BA1BS2_Supporting

This summary comes from the ClinGen Evidence Repository: The c.731C>T (NM_002185.5) variant in IL7R is a missense variant predicted to cause substitution of Threonine by Isoleucine at amino acid 244 (p.Thr244Ile).The filtering allele frequency (the lower threshold of the 95% CI of 21695/63972 alleles) of the c.731C>T variant in IL7R is 0.2678 for European (non-Finnish) chromosomes by gnomAD v4, which is higher than the ClinGen SCID VCEP threshold (>0.00566) for BA1, and therefore meets this criterion (BA1). Additionally, 53760 homozygous adults are reported in gnomAD v.4. 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, as specified by the ClinGen SCID-VCEP: BA1 and BS2_Supporting. (VCEP specifications version 1). LINK:https://erepo.genome.network/evrepo/ui/classification/CA160105/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]

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. -
