Cytopenias and congenital anaemias
Gene: ADAMTS13The classic pentad of familial thrombotic thrombocytopenic purpura (TTP) includes hemolytic anemia with fragmentation of erythrocytes and thrombocytopenia (amongst other symptoms). Thromobocytopaenia is currently out the scope for this panel unless criteria is widened to platelet disorders. Discussed with Helen Brittain who agrees that hemolytic anemia should be included since pancyto or bi-cytopaenia are included in the inclusion criteria, and this counts as bi- in view of red cells and platelets being involved.Created: 9 Mar 2017, 11:52 a.m.
Comment when marking as ready: Rated green after clinican discussion. Hemolytic anemia phenotype is relevant to the panel. Sufficient cases to support causation.Created: 9 Mar 2017, 11:37 a.m.
Comment on list classification: Updated rating from Red to Green: Although thrombocytopenia is out of scope for this panel, after feedback from Arianna, I included ADAMTS13 on this panel because of the hemolytic anemia phenotype seen with TTP disorder (bi-cytopenia =loss of red blood cells and platelets). >3 cases supporting association between ADAMTS13 and TTP (MIM:274150).Created: 8 Mar 2017, 10:07 a.m.
Phenotypes for gene: ADAMTS13 were changed from Familial Thrombotic Thrombocytopenia Purpura; Thrombotic thrombocytopenic purpura, familial, 274150 to Thrombotic thrombocytopenic purpura, hereditary, OMIM:274150
