Genetic study in association with pre-transplant PVT in liver recipients

	With Pre-transplant PVT (50 cases)	Without Pre-transplant PVT(221 cases)	Significance
RECIPIENT STUDY
Factor V Leiden mutation(Nº)(heterozygous) in recipient	1/49	6/215	p = 0.774
Prothrombin 20210A mutation(Nº)(heterozygous) in recipient	1/49	12/209	p = 0.305
C677T MTHFR mutation (Nº) (wild type/heterozygous/homozygous) in recipient	18/23/7	87/93/33	p = 0.865

The study was conducted in 271 liver recipients. The MTHFR C677T genotype was not tested in ten cases. PVT, portal vein thrombosis; MTHFR, 5,10-methylene-tetrahydrofolate reductase.
