Summaries for Bleeding Disorder, Platelet-Type, 21

OMIM : 58 BDPLT21 is a hematologic disorder characterized by increased risk of bleeding resulting from a functional platelet defect. Platelets have decreased or even absent dense bodies and abnormally enlarged and fused alpha-granules, and they show defective secretion and aggregation responses to agonists. Platelets are usually enlarged, and some patients may have mild to moderate thrombocytopenia (summary by Saultier et al., 2017). For a discussion of genetic heterogeneity of platelet-type bleeding disorders, see BDPLT1 (231200). (617443)

MalaCards based summary : Bleeding Disorder, Platelet-Type, 21, is also known as bdplt21. An important gene associated with Bleeding Disorder, Platelet-Type, 21 is FLI1 (Fli-1 Proto-Oncogene, ETS Transcription Factor). Related phenotypes are thrombocytopenia and eczema

UniProtKB/Swiss-Prot : 76 Bleeding disorder, platelet-type 21: A disorder characterized by increased bleeding tendency due to platelet dysfunction. Clinical features include epistaxis, hematomas, bleeding after tooth extraction, and menorrhagia. BDPLT21 patients may have mild to moderate thrombocytopenia.
