Abstract

Combined factor V and factor VIII deficiency (F5F8D) is a rare autosomal recessive coagulation disorder associated with plasma levels of coagulation factors V and VIII approximately 5% to 30% normal. Combined factor V and factor VIII deficiency is caused by mutations in ERGIC-53 (LMAN1) gene. ERGIC-53 and multiple coagulation factor deficiency 2 (MCFD2) form a protein complex that functions as a cargo receptor transport FV and FVIII from the endoplasmic reticulum to the Golgi. The aim of this study was to determine the mutations of ERGIC-53 (endoplasmic reticulum [ER] to the ER-Golgi intermediate compartment) gene and combined F5F8D in a family. In this study, we analyzed a patient in a Turkish family with combined F5F8D. We found a nonsense mutation of C to T at nucleotide 202 in exon 9, resulting in a transition of arginine to stop codon, and in 1 child, we found a timine deletion in exon 4 in ERGIC-53 gene.
