Familial monozygotic twinning: a report of seven pedigrees.
Seven families contained 19 MZ twin pairs (2.7 pairs/family), diagnosed by low-stringency variable number tandem repeats in DNA from placental tissue or blood. Chorion status was known in 10 pairs, 6 dichorionic, 4 monochorionic. Sex ratio was equal. Autosomal dominant inheritance is apparent.
