Case Report: Identification of Germline Chimerism in Monochorionic Dizygotic Twins

Frontiers in Genetics, 2021
Monochorionic twins are generally considered to be monozygotic, as monochorionic dizygotic (MCDZ) twins are extremely rare in natural pregnancies. Several studies have reported this rare occurrence, and most of these pregnancies have been conceived by ...
