Premarital Screening Program for Congenital Factor XIII Deficiency in Iran.

BACKGROUND

Factor XIII deficiency is one of the most severe congenital bleeding disorders with high rate of life-threatening bleeding including central nervous system bleeding, umbilical cord bleeding, and recurrent miscarriages. Due to the highest global incidence of the disorder in Iran, this study aimed to design a premarital screening program in Iran.

METHODS

This descriptive study was performed on 30 couples with a positive family history of factor XIII deficiency. Underling F13A gene mutation was determined in the family members, and all the selected couples underwent molecular testing mutations by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), tetra primer-amplification refractory mutation system-PCR (T-ARMS-PCR), and sequencing.

RESULTS

The probability of affected childbirth existed for ten couples. Three couples decided not to marry, while seven got married and three of them decided to have a baby. The genotypes of the fetuses were determined and revealed that none of them was a homozygote for the F13A gene mutation.

CONCLUSIONS

Because of the importance of factor XIII deficiency diagnosis, it can be helpful to control the incidence of factor XIII deficiency by implementing preventive programs such as premarital screening.
