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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

BS1
Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000854 (13/152194) while in subpopulation EAS AF= 0.00192 (10/5198). AF 95% confidence interval is 0.00104. There are 1 homozygotes in gnomad4. There are 6 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.

Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This sequence change replaces histidine, which is basic and polar, with tyrosine, which is neutral and polar, at codon 154 of the IL7R protein (p.His154Tyr). This variant is present in population databases (rs199727195, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with IL7R-related conditions. ClinVar contains an entry for this variant (Variation ID: 134525). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt IL7R protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
