Decoding the Genetics of Recurrent Molar Pregnancy.

Hydatidiform mole is a condition characterised by abnormal trophoblastic hyperplasia and failure of embryonic tissue development. The risk of recurrence is seen to be associated with biallelic maternal mutations in , and genes. Women with such mutations have a major risk of reproductive failure and normal pregnancy is seen in only 1.8%. We report the case of a 31-year-old woman with previous three molar pregnancies who on genetic testing was found to be compound heterozygous for pathogenic variants in the gene (c.2738A>G and c.2078G>C). Accordingly, the woman was counselled regarding assisted reproduction with oocyte donation for a normal pregnancy outcome. At present, the patient has an ongoing 5-month pregnancy through oocyte donation.
