- immunodeficiency 35 [DOID:0111989]
A primary immunodeficiency disease characterized by increased susceptibility to mycobacterial infection after BCG vaccination and impaired cellular responses to IL-12, IFN-alpha/beta, IL-23, and IL-10 that has_material_basis_in homozygous or compound heterozygous mutation in the TYK2 gene on chromosome 19p13.2.
- interleukin-7 receptor alpha deficiency [DOID:0060015]
A severe combined immunodeficiency that results from defective IL7R expression causes T-B+NK+ SCID. Loss of IL-7R function leads to the loss of an antiapoptotic signal, resulting in a loss of T-cell selection in thymus.
- X-linked severe combined immunodeficiency [DOID:0060013]
A severe combined immunodeficiency that is a X-linked SCID that has_material_basis_in mutations in genes encoding common gamma chain proteins shared by the interleukin (IL-2,4,7,9,16 and21) receptors resulting in a non-functional gamma chain, defective interleukin signalling, minimal or ascent T- and NK cells and non-functional B-cells.
