- immunodeficiency 49 [DOID:0111979]
A T cell deficiency characterized by T cell lymphopenia, low T-cell receptor excision circles, impaired T-cell proliferative responses, dysmorphic facial features, hypotonia and severe global developmental delay that has_material_basis_in heterozygous mutation in BCL11B on chromosome 14q32.2.
- immunodeficiency 48 [DOID:0111943]
A T cell deficiency characterized by a selective T cell defect where circulating T cells exclusively express CD4, CD3, and T-cell receptor-alpha/beta and not CD8 on their surfaces that has_material_basis_in homozygous or compound heterozygous mutation in ZAP70 on chromosome 2q11.2.
- immunodeficiency 13 [DOID:0111987]
A T cell deficiency characterized by decreased CD4 T-lymphocyte counts that has_material_basis_in heterozygous mutation in UNC119 on chromosome 17q11.2.
- immunodeficiency 23 [DOID:0111953]
A combined T cell and B cells immunodeficiency characterized by marked atopy and autoimmunity caused by increased T(H)2 and T(H)17 cytokine production by CD4(+) T cells, T-cell lymphopenia, reduced memory B-cell numbers, recurrent respiratory and skin infections beginning in early childhood, increased serum IgE, and variable developmental delay or intellectual impairment that has_material_basis_in homozygous or compound heterozygous mutation in PGM3 on chromosome 6q14.1.
- immunodeficiency 53 [DOID:0111992]
A combined T cell and B cell immunodeficiency characterized by recurrent upper and lower respiratory infections, increase in the CD4+ T cell to CD8+ T cell ratio, impaired T-cell proliferative responses to multiple antigens, and impaired ability to produce specific immunoglobulins that has_material_basis_in homozygous or compound heterozygous mutation in RELB on chromosome 19q13.32.
- adult T-cell leukemia [DOID:0050523]
A T-cell leukemia that results_in abnormal increase of lymphocytes, derives_from T-cells, has_material_basis_in Human T-lymphotropic virus 1, which is transmitted_by sexual contact, transmitted_by contaminated needles used by intravenous-drug users, and transmitted_by breast feeding. The infection results_in_formation_of skin lesions.
