- immunodeficiency 46 [DOID:0111948]
A combined T cell and B cell immunodeficiency characterized by hypo- or agammaglobulinemia, normal lymphocyte counts, intermittent neutropenia, intermittent thrombocytopenia, decreased numbers of memory B cells, impaired immunoglobulin class-switching, and decreased proliferative responses of T cells that has_material_basis_in homozygous or compound heterozygous mutation in the TFRC gene on chromosome 3q29.
- immunodeficiency with hyper IgM type 5 [DOID:0060759]
A hyper IgM syndrome that is characterized by normal or increased serum IgM concentrations associated with low or absent serum IgG, IgA, and IgE concentrations, indicating a defect in the class-switch recombination (CSR) process that has_material_basis_in homozygous or compound heterozygous mutation in the UNG gene on chromosome 12q23-q24.1.
- torsion dystonia 4 [DOID:0090041]
A dystonia that is characterized by progressive laryngeal and cervical dystonia (onset in the second to third decade of life) followed by involvement of other muscles, such as the neck or limbs that has_material_basis_in autosomal dominant inheritance of heterozygous mutation in the tubulin beta 4A class IVa (TUBB4A) gene on chromosome 19p13.
- immunodeficiency 56 [DOID:0111982]
A combined T cell and B cell immunodeficiency characterized by B- and T-cell defects including defective class-switched B cells, low IgG, defective antibody response, and defective T-cell responses to certain antigens, and variable dysfunction of NK cells that has_material_basis_in homozygous or compound heterozygous mutation in the IL21R gene on chromosome 16p12.1.
