Twins and twinning.
Hall JG. Hall JG. Am J Med Genet. 1996 Jan 22;61(3):202-4. doi: 10.1002/(SICI)1096-8628(19960122)61:3<202::AID-AJMG2>3.0.CO;2-W. Am J Med Genet. 1996. PMID: 8741863 Review. No abstract available.
Prematurity and twinning.
Giuffrè M, Piro E, Corsello G. Giuffrè M, et al. J Matern Fetal Neonatal Med. 2012 Oct;25 Suppl 3:6-10. doi: 10.3109/14767058.2012.712350. J Matern Fetal Neonatal Med. 2012. PMID: 23016610 Review.
Prematurity is the main reason for most neonatal diseases in twins, but other variables may play a role and their prenatal evaluation may improve the overall outcome. MAIN FINDINGS: Prematurity is six times more frequent in twins and therefore birth weight is signif …

A review of the mechanisms and evidence for typical and atypical twinning.
McNamara HC, Kane SC, Craig JM, Short RV, Umstad MP. McNamara HC, et al. Am J Obstet Gynecol. 2016 Feb;214(2):172-191. doi: 10.1016/j.ajog.2015.10.930. Epub 2015 Nov 6. Am J Obstet Gynecol. 2016. PMID: 26548710 Review.
This article presents a review of the literature focusing on twinning and atypical twinning with an emphasis on the phenomena of chimeric twins, phenotypically discordant monozygotic twins, mirror-image twins, polar body twins, complete h …

Twinning: mechanisms and genetic implications.
Hall JG. Hall JG. Curr Opin Genet Dev. 1996 Jun;6(3):343-7. doi: 10.1016/s0959-437x(96)80012-8. Curr Opin Genet Dev. 1996. PMID: 8791516 Review.
In the past, twins have been studied to determine the genetic contribution to various disease processes. Recent work, however, suggests that monozygotic (MZ) twins are not truly identical. Many genetic forms of discordance have been described within MZ twin pairs an …

Dizygotic twinning as a measure of human fertility.
Tong S, Short RV. Tong S, et al. Hum Reprod. 1998 Jan;13(1):95-8. doi: 10.1093/humrep/13.1.95. Hum Reprod. 1998. PMID: 9512236 Review.
Monozygotic twinning rates have remained remarkably constant or increased only very slightly in recent decades. This makes it possible to use the dizygotic:monozygotic twinning ratio to monitor dizygotic twinning in populations where true incidence rates cann …

Twinning rates.
Murphy M, Hey K. Murphy M, et al. Lancet. 1997 May 10;349(9062):1398-9. doi: 10.1016/s0140-6736(05)63241-2. Lancet. 1997. PMID: 9149727 No abstract available.
Twinning on the brain: the effect on neurodevelopmental outcomes.
Luu TM, Vohr B. Luu TM, et al. Am J Med Genet C Semin Med Genet. 2009 May 15;151C(2):142-7. doi: 10.1002/ajmg.c.30208. Am J Med Genet C Semin Med Genet. 2009. PMID: 19378331 Review.
Twinning is currently considered a complex multifactorial trait. Few studies have explored how the unique genetic and environmental influences that create twinning affect phenotypes and outcomes. ...The purpose of this review is to report primarily on neuromotor out …

Twinning and mitotic crossing-over: some possibilities and their implications.
Côté GB, Gyftodimou J. Côté GB, et al. Am J Hum Genet. 1991 Jul;49(1):120-30. Am J Hum Genet. 1991. PMID: 2063864 Free PMC article. Review.
Some predictions are at odds with classical views on twinning and include a high discordance rate of MZ twins for some genetic diseases. A review of MZ twin discordance and an attempt at explaining some of the data lead one to hypothesize both the existence of a sex …

The Genetics of Human DZ Twinning.
Boomsma DI. Boomsma DI. Twin Res Hum Genet. 2020 Apr;23(2):74-76. doi: 10.1017/thg.2020.15. Epub 2020 May 8. Twin Res Hum Genet. 2020. PMID: 32383427
In the course of twin studies whose main focus was elucidation of genetic and environmental factors on behavioral traits, many twin researchers became aware of the strong tendency for dizygotic (DZ) twinning to run in families. Over four decades, Nick Martin and others ini …
