- Loeys-Dietz syndrome 6 [DOID:0060964]
A Loeys-Dietz syndrome characterized by aortic/arterial aneurysm and dissection in association with connective tissue findings that has_material_basis_in heterozygous mutation in the SMAD2 gene (601366) on chromosome 18q21.
- Meester-Loeys syndrome [DOID:0111861]
A syndrome characterized by early-onset aortic aneurysm and dissection in hemizygous males and variable presentation from unaffected to fatal aortic dissection in heterozygous females, as well as facial dysmorphism, connective tissue anomalies, and features of Loeys-Dietz syndrome that has_material_basis_in mutation in BGN on chromosome Xq28.
- vitamin K deficiency bleeding [DOID:11249]
A nutritional deficiency disease that is characterized by easy bleeding due to an inability to form blood clots caused by vitamin K deficiency, occurs most commonly in newborns, and has_material_basis_in deficiency of vitamin K secondary to liver prematurity, lack of vitamin K in a breastmilk diet, largely sterile gut, malabsorption, diarrhea, chronic illness, menorrhagia, chronic kidney disease, and some medications.
- hereditary combined deficiency of vitamin K-dependent clotting factors [DOID:0112172]
A blood coagulation disease characterized by reduced hepatic gamma-carboxylation of glutamic acid residues of all vitamin K-dependent blood coagulation factors and the anticoagulant factors protein C and protein S resulting in a bleeding tendency that is usually reversed by oral administration of vitamin K that has_material_basis_in a heritable mutation.
