- second-degree atrioventricular block [DOID:0050822]
An atrioventricular block that is characterized by progressive prolongation of the PR interval on consecutive beats followed by a blocked P wave on electrocardiogram or intermittently non-conducted P waves not preceded by PR changes on electrocardiogram caused by a conduction block between the atria and the ventricles through the atrioventricular node.
- pentosuria [DOID:0111258]
An amino acid metabolic disorder characterized by excretion of excess pentose L-xylulose (1-4 g/day) in the urine that has_material_basis_in homozygous or compound heterozygous mutation in DCXR on 17q25.3.
- glycine encephalopathy 1 [DOID:0070616]
A glycine encephalopathy that has_material_basis_in homozygous or compound heterozygous mutation in the GLDC gene, a member of the mitochondrial glycine cleavage system that encodes the P protein, on chromosome 9p24.
- third-degree atrioventricular block [DOID:0050823]
An atrioventricular block that is characterized by bradycardia, hypotension, hemodynamic instability and complete dissociation between P waves and QRS complexes on electrocardiogram caused when conduction fails to propagate from atria to ventricles.
- amelogenesis imperfecta type 2A6 [DOID:0080960]
An amelogenesis imperfecta that is characterized by enamel of normal thickness that is hypomineralized and has a mottled appearance and that has_material_basis_in homozygous mutation in the G protein-coupled receptor-68 (GPR68) on chromosome 14q32.
- immunodeficiency 31B [DOID:0111944]
A primary immunodeficiency disease characterized by impaired cellular responses to interferons A, B, and G resulting increased susceptibility to mycobacteria, Salmonella, and viruses that has_material_basis_in homozygous or compound heterozygous mutation in the STAT1 gene on chromosome 2q32.2.
- chromosome 16p12.1 deletion syndrome [DOID:0060399]
A chromosomal deletion syndrome that has_material_basis_in a 520 kb deletion on the short (p) arm of the chromosome at a location designated 16p12.1 and is characterized by developmental delay, craniofacial dysmorphology, and congenital heart defects.
- severe congenital neutropenia 5 [DOID:0112132]
A severe congenital neutropenia characterized by neutropenia and neutrophil dysfunction, a lack of response to G-CSF, life-threatening infections, bone marrow fibrosis, and renal extramedullary hematopoiesis that has_material_basis_in homozygous or compound heterozygous mutation in the VPS45 gene on chromosome 1q21.2.
- immunodeficiency 43 [DOID:0111981]
A primary immunodeficiency disease characterized by recurrent infections, reduced serum concentrations of immunoglobulin G and albumin due to rapid degradation of these proteins, abnormal renal or liver function, and excessive gastrointestinal protein that has_material_basis_in homozygous or compound heterozygous mutation in B2M on chromosome 15q21.1.
