ABSTRACT
OBJECTIVE To study the imprinting status of H19 gene in normal villi tissue during the first trimester,and its relation to the invasion of trophoblast. METHODS Using PCR-RFLP methods to examine the imprinting status of H19 gene in 93 cases of normal villi tissue during the first trimester. RESULTS Among 93 cases, heterozygous genotypes were found in 42 cases. And 11 cases of biallelic expression were found among these 42 cases of heterozygous genotypes from 5 to 9 weeks, however no biallelic expression existed from 10 to 12 weeks. CONCLUSIONS During the first trimester, H19 is expressed biallelically at the first 10 weeks. The H19 gene may dynamicly change in the trophoblast, and the dynamic change may have close relationship with the invasion of the trophoblast.
