Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS1

This summary comes from the ClinGen Evidence Repository: NM_002185.5(IL7R):c.152C>T is a missense variant predicted to cause substitution of Serine by Leucine at amino acid 51 (p.Ser51Leu). The filtering allele frequency (the lower threshold of the 95% CI of 110/74978) of the c.152C>T variant in IL7R is 0.001270 for African/African American chromosomes by gnomAD v4, which is higher than the ClinGen SCID VCEP threshold (>0.00126) for BS1, and therefore meets this criterion (BS1). To our knowledge, this variant has not been reported in the literature in individuals affected with IL7R-related conditions or in functional studies.As per SCID VCEP specifications, 1 Strong criteria is enough to reach Likely Benign classification. In summary, this variant meets the criteria to be classified as a Likely Benign variant for autosomal recessive severe combined immunodeficiency due to IL7R deficiency based on the ACMG/AMP criteria applied, as specified by the ClinGen SCID VCEP: BS1 (VCEP specifications version 1).

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]
