Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BA1BS2_Supporting

This summary comes from the ClinGen Evidence Repository: The c.1066A>G (NM_002185.5) variant in IL7R is a missense variant predicted to cause substitution of Isoleucine by Valine at amino acid 356 (p.Ile356Val).The filtering allele frequency (the lower threshold of the 95% CI of 25619/74900 alleles) of the c.1066A>G variant in IL7R is 0.3385 for African/African American chromosomes by gnomAD v4, which is higher than the ClinGen SCID VCEP threshold (>0.00566) for BA1, and therefore meets this criterion (BA1). Additionally, 55069 adult homozygous occurrences are described in gnomAD (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.

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]
