- Sengers syndrome [DOID:0080132]
A mitochondrial DNA depletion syndrome that is characterized by congenital cataracts, hypertrophic cardiomyopathy, skeletal myopathy, exercise intolerance, and lactic acidosis, but normal mental development, and has_material_basis_in autosomal recessive inheritance of homozygous or compound heterozygous mutation in the acylglycerol kinase gene on chromosome 7q34.
- xeroderma pigmentosum variant type [DOID:0110847]
A xeroderma pigmentosum characterized by normal DNA excision repair, but defective postreplication repair that has_material_basis_in mutations in the POLH gene on chromosome 6p21.1.
- mitochondrial DNA depletion syndrome 13 [DOID:0080131]
A mitochondrial DNA depletion syndrome that is characterized by early infantile onset of encephalopathy, hypotonia, lactic acidosis, and severe global developmental delay, and has_material_basis_in autosomal recessive inheritance of homozygous mutation in the F-box and leucine-rich repeat protein 4 gene on chromosome 6q16.
- mitochondrial DNA depletion syndrome 16B [DOID:0070447]
A mitochondrial DNA depletion syndrome characterized by childhood onset of progressive neuroophthalmic manifestation including optic atrophy, mixed polyneuropathy, spinal and cerebellar ataxia and generalized chorea that has_material_basis_in homozygous mutation in the POLG2 gene on chromosome 17q23.
- mitochondrial DNA depletion syndrome 20 [DOID:0070451]
A mitochondrial DNA depletion syndrome characterized by variable neurogastrointestinal encephalopathy including severe gastrointestinal dysmotility, neurogenic bladder, muscle weakness and atrophy, headaches, stroke-like episodes, seizures, pyramidal signs, and learning difficulties or cognitive decline that has_material_basis_in compound heterozygous mutation in the LIG3 gene on chromosome 17q12.
- mitochondrial DNA depletion syndrome 2 [DOID:0080120]
A mitochondrial DNA depletion syndrome that is characterized by childhood onset of muscle weakness associated with depletion of mtDNA in skeletal muscle, and has_material_basis_in autosomal recessive inheritance of homozygous or compound heterozygous mutation in the mitochondrial thymidine kinase gene on chromosome 16q21.
- mitochondrial DNA depletion syndrome 6 [DOID:0080125]
A mitochondrial DNA depletion syndrome that is characterized by infantile onset of progressive liver failure, often leading to death in the first year of life, and has_material_basis_in autosomal recessive inheritance of homozygous or compound heterozygous mutation in the mitochondrial inner membrane protein MPV17 gene on chromosome 2p23.
- 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.
