    Introduction: Rare factor deficiencies are predominantly autosomal recessively inherited disorders with a frequency of approximately 1: 500000 to 1: 2000000 in the general population. They account for 3-5% of all inherited coagulation disorders. In this study, we aimed to evaluate the demographic features and clinical findings of 36 patients who were followed up and treated with the diagnosis of rare factor deficiency. Materials and Methods: A total of 36 patients aged between 0-16 years diagnosed with rare coagulation deficiencies were evaluated in terms of demographic, physical examination, clinical follow-up, and laboratory findings at the Dicle University Pediatric Hematology Unit. Ethics committee approval was obtained from Dicle University for the study on 16.03.2018 with decision no 115. Results: Rare factor deficiencies were diagnosed in 36 (35 %) of 103 patients who were followed up with coagulation disorders. Hemophilia a, hemophilia b, and von Willebrand disease constituted 67 of our patients. Familial consanguinity was present in 75, 6 %, and positive family history was found at 16.6% of the patients. 11 (32.4%) of our patients were diagnosed under the age of one year. Most of our patients diagnosed with factor X deficiency (38.8%). The most common symptoms were mucocutaneous bleeding (50%). Intracranial hemorrhage was detected in 7 (%19,5) patients. Conclusions: Early diagnosis and treatment are very important in the case of rare factor deficiency since severe bleeding complications such as intracranial hemorrhage may develop. Rare factor deficiencies are seen more frequently in places where consanguineous marriage is more common than the general population. Families should be informed about this issue, and family screening should be done early.
