Forty-seven patients (male : female ratio = 1.2 : 1) were included. The majority (93.6%) have parental history of consanguinity and around one third (31.9%) have family history of bleeding disorder. FV deficiency was the most common deficient factor (36.2%) followed by FI deficiency (23.4%) and FX111 deficiency (21.3%). Bruising (46.8%) and epistaxis (25.5%) were the most common presenting complains. FV deficiency mainly presented with cutaneous ecchymosis (47.1%). FI deficiency presented with umbilical bleeding (45.5%) and FXIII presented with cutaneous ecchymosis (50%). Rare clotting factor deficiency is an existing disease in Sudan with the male : female ratio was 1.2 : 1. FV deficiency, FI deficiency, FXIII deficiency were the common deficiency encountered.
