Genetic Variant IL7R:c.82+14A>T (chr5-35857073-A-T) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 1P and 1B. PM2_SupportingBP7

This summary comes from the ClinGen Evidence Repository: The c.82+14A>T (NM_002185.5) variant in IL7R is an intronic variant which locates in the deep intronic region in intron 1. It is not predicted to impact splicing by SpliceAI, varSEAK, and NNSplice. BP7 is met.This variant is absent from gnomAD v2.1.1 (PM2_Supporting).In summary, this variant is classified as uncertain significance for autosomal recessive SCID based on ACMG/AMP criteria applied, as specified by the ClinGen SCID VCEP (specification version 1.0): PM2_Supporting and BP7.

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]
