Application of next-generation sequencing to preimplantation genetic testing for recurrent hydatidiform mole patients.

Analyzing the copy number variants and the numbers of heterozygous single nucleotide polymorphism on the basis of next-generation sequencing can be utilized in the procedure of preimplantation genetic testing among part of recurrent hydatidiform mole patients. The current study is effective to reduce the occurrence of hydatidiform mole with improved clinical strategy, the advanced testing technology and analysis methods, as three of seven patients have conceived or delivered successfully.
