Monozygotic triplets: concordance and discordance for cleft lip and palate / twin research reviews: depression in mothers of multiples; depression in mothers and fathers of ART conceived multiples; epigenetic differences in monozygotic twins; congenital anomalies in surviving twins / headlines x two: twin Chefs; the world's largest twin registry; twin table tennis champions.
A review of twin research on cleft lip and palate is presented. This information is accompanied by a look at the lives of young monozygotic (MZ) male triplets concordant for cleft lip, but discordant for the type and placement of the cleft and for the presence of cleft palate. Research on depression in mothers and fathers of twins conceived naturally and by artificial reproductive techniques follows. Current findings and implications of epigenetic differences in MZ twins are also summarized. Interesting life history events surrounding MZ twin chefs and table tennis players, as well as plans to construct the world's largest twin registry, are presented in the final section.
