摘要：
Congenital combined vitamin K-dependent clotting factors deficiency (VKCFD) is a very rare autosomal recessive bleeding disorder. Here we report a case of a girl with novel variant in the gamma-glutamyl carboxylase (GGCX) gene leading to VKCFD. A 3-month-old girl presented to our hospital with a history of bleeding from puncture site. Laboratory evaluation showed markedly prolonged partial thromboplastin time and activated partial thromboplastin time. Activities of vitamin K-dependent factors were all low. Genetic analysis revealed a homozygous currently unreported variant in the GGCX gene further supporting a diagnosis of VKCFD type 1. VKCFD due to GGCX mutation has an overall good prognosis
