Clinical validity: Help
Identification of causal mutations have enhanced the diagnosis of inherited thrombocytopenia, however, the clinical sensitivity is still thought to be around 50 %. We sequenced one positive control sample from a patient diagnosed with thrombocytopenia. In this case, we identified a pathogenic variant along with other SNVs, suggesting the clinical … View more

Test Comments: Help
Inherited thrombocytopenia is a group of heterogenous blood disorders characterized by low platelet counts; typically less than 150,000/uL. Symptoms include excessive bruising (purpura), petechiae, prolonged bleeding from cuts, spontaneous nose bleeds, and heavy menstrual flows in women. Inherited thrombocytopenia may follow either autosomal dominant, autosomal recessive, or X-linked inheritance. Severe … View more
