Birth of a Healthy Monozygotic Twin Foal with Hydrops and a Dead Co-Twin [PDF]

open access: yesVeterinary Sciences
Transfer of in vitro-produced (IVP) equine embryos is associated with a higher incidence of monozygotic multiple pregnancies, but this remains a rarity. The outcome of monozygotic twin gestation is poor, and good management techniques are lacking.

Indian twin registry: A gold mine for genetic studies

open access: yesAsian Journal of Medical Sciences, 2023
Twins are a source of curiosity, both for the family and the scientific community. Genetic similarities between twins have been the preferred choice to study the heritability of traits.

Lifetime socioeconomic position and twins' health: an analysis of 308 pairs of United States women twins. [PDF]

open access: yesPLoS Medicine, 2005
Important controversies exist about the extent to which people's health status as adults is shaped by their living conditions in early life compared to adulthood. These debates have important policy implications, and one obstacle to resolving them is the

Vertical Transmission and Discordance of Cytomegalovirus in Twin Pregnancies

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
ObjectiveThe objectives are to estimate the vertical transmission rate in twins relative to singleton pregnancies, to evaluate whether discordance within twin pairs is rare, and to characterize concordance within monozygotic and dizygotic twin pairs in ...

Monozygotic Heterocaryotic Twinning [PDF]

open access: yesActa geneticae medicae et gemellologiae, 1974
Since the first publication in 1961, cases of monozygotic heterocaryotic twinning have been repeatedly found and a total of 14 observations can now be analysed. The mechanism involved in this type of twinning is yet uncertain and eventually is not identical in each case, the main uncertainty being to decide whether the chromosomal error affecting one ...

Simultaneous presentation of idiopathic uveitis in monozygotic 4-year-old twin boys

open access: yesAmerican Journal of Ophthalmology Case Reports, 2022
Purpose: To report monozygotic twin 4-year-old boys with chronic bilateral anterior uveitis with simultaneous onset. Observations: Here we report monozygotic twin 4-year-old boys with chronic bilateral anterior uveitis. The boys had simultaneous onset of

Monozygotic twin sisters discordant for familial hemiplegic migraine [PDF]

open access: yes, 2013
Background: The high concordance rate of migraine in monozygotic twin pairs has long been recognised. In the current study, we present a monozygotic twin pair discordant for familial hemiplegic migraine (FHM).

Monozygotic twins discordant for trisomy 21: Discussion of etiological events involved

open access: yesTaiwanese Journal of Obstetrics & Gynecology, 2017
Objective: To elucidate the etiologies of discordant trisomy 21 in monozygotic twin pregnancy. Case report: A monochorionic diamniotic twin pregnancy with hydrops and cleft lip (twin 1) found in one fetus presented at gestational age of 17 weeks ...

Intra-Monozygotic Twin Pair Discordance and Longitudinal Variation of Whole-Genome Scale DNA Methylation in Adults. [PDF]

open access: yesPLoS ONE, 2015
Monozygotic twins share identical genomic DNA and are indistinguishable using conventional genetic markers. Increasing evidence indicates that monozygotic twins are epigenetically distinct, suggesting that a comparison between DNA methylation patterns ...
