An estimated 12% of severe combined immunodeficiency (SCID) is caused by pathogenic variants identified in IL7R (PMID: 25138334).
IL7R encodes the interleukin 7 (IL-7) receptor alpha chain which is a subunit of the IL-7 receptor and the thymic stromal lymphopoietin (TSLP) receptor. The IL-7 receptor is located in the cell membrane of B and T cells as well as their precursors, while TSLP receptor is in the cell membrane of a number of cell types including T cells, B cells, monocytes and dendritic cells. IL-7 is a cytokine that binds to the IL-7 receptor triggering signaling for the development of mature T and B cells. The TSLP cytokine binds to the TSLP receptor triggering signaling for the proliferation and maturation of immune cells (PMID: 26235889).
Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).
Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.
Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
