- DNA ligase IV deficiency [DOID:0060021]
A combined T cell and B cell immunodeficiency that has_material_basis_in a mutation in the LIG4 gene, a DNA ligase, encoding a protein essential for V(D)J recombination and DNA double-strand break (DSB) repair through nonhomologous end joining (NHEJ). Patients present with immunodeficiency and developmental and growth delay.
- immunodeficiency 26 [DOID:0111961]
A severe combined immunodeficiency characterized by virtually absent peripheral B and T cells but normal numbers of NK cells, complete block in B-cell differentiation, and a defect in slow repair of DNA double-strand breaks in fibroblasts, that has_material_basis_in homozygous or compound heterozygous mutation in the PRKDC gene on chromosome 8q11.21.
- hypertrophic cardiomyopathy 4 [DOID:0110310]
