- 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 the BCL11B gene on chromosome 14q32.2.
- seborrheic infantile dermatitis [DOID:8941]
A seborrheic dermatitis that involves fungal infection of the scalp of recently born babies caused by Malassezia furfur. It is occasionally linked to immune disorders. The symptoms include thick, crusty, yellow or brown scales over the child's scalp.
- 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 the ZAP70 gene on chromosome 2q11.2.
- hepatosplenic T-cell lymphoma [DOID:0081049]
A mature T-cell and NK-cell lymphoma that is characterized by the presence of medium-size neoplastic lymphocytes infiltrating the hepatic sinusoids and that originates from cytotoxic T-cells, usually of gamma/delta T-cell type.
- immunodeficiency 13 [DOID:0111987]
A T cell deficiency characterized by decreased CD4 T-lymphocyte counts that has_material_basis_in heterozygous mutation in the UNC119 gene 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 the PGM3 gene on chromosome 6q14.1.
