Question: Is recurrent hydatidiform mole inherited ?
Answer: This condition is often inherited in an autosomal recessive pattern, which means a woman has to have mutations in both copies of the gene in each of her cells to have recurrent hydatidiform mole pregnancies. Because the mutations are present in all of a woman's cells, including oocytes (which need these genes to promote normal embryonic development), a hydatidiform mole will develop in each pregnancy that occurs with those egg cells.
