The Impact of Environmental and Genetic Factors on Bone Quality in Monozygotic and Dizygotic Twins [PDF]
Biomedicines, 2022 The purpose of the research was to assess the genetic and environmental influences on bone properties. One hundred thirty-two pairs of twins (99/33 monozygotic/dizygotic) underwent anthropometric measurements and phalangeal quantitative ultrasound (DBM ...

Rare spontaneous monochorionic dizygotic twins: a case report and a systematic review [PDF]
BMC Pregnancy and Childbirth, 2022 Background Monochorionic dizygotic twins are a rare condition, mostly related to assisted reproductive technology. This type of twinning is burdened by the same risk of pregnancy complications found in monochorionic monozygotic pregnancies.

Confined Blood Chimerism in Monochorionic Dizygotic Twins Conceived Spontaneously
American Journal of Perinatology Reports, 2013 Traditionally, monochorionicity has been regarded as synonymous with monozygosity. However, several recent cases of monochorionic dizygotic twins have shown that monochorionic twins can be dizygous.

Case Report: Identification of Germline Chimerism in Monochorionic Dizygotic Twins [PDF]
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 ...

Characterizing genetic and environmental influences on variable DNA methylation using monozygotic and dizygotic twins. [PDF]
PLoS Genet, 2018 Variation in DNA methylation is being increasingly associated with health and disease outcomes. Although DNA methylation is hypothesized to be a mechanism by which both genetic and non-genetic factors can influence the regulation of gene expression ...

Human Reproduction Update, 2007 The tendency to conceive spontaneous dizygotic (DZ) twins is a complex trait with important contributions from both environmental factors and genetic disposition. Twins are relatively common and occur on average 13 times per 1000 maternities, though the twinning frequency varies over time and geographic location.

A genome wide linkage scan for dizygotic twinning in 525 families of mothers of dizygotic twins [PDF]
Human Reproduction, 2010 The tendency to conceive dizygotic (DZ) twins is a complex trait influenced by genetic and environmental factors. To search for new candidate loci for twinning, we conducted a genome-wide linkage scan in 525 families using microsatellite and single nucleotide polymorphism marker panels.Non-parametric linkage analyses, including 523 families containing ...

Simultaneous cloacogenic carcinoma in dizygotic twins [PDF]
Cancer, 1987 Dizygotic twins developed cloacogenic carcinoma of the anus almost simultaneously. The patients, although separated from the time they were 20-years-old, had very similar life styles. There are several reports in the medical literature of synchronous tumors in mono and dizygotic twins.

In Utero Diagnoses of Strikingly Similar Presentations of Complete Atrioventricular Septal Defects in a Pair of Dizygotic Twins Concordant for Trisomy 21 [PDF]
Case Reports in Pediatrics, 2018 Trisomy 21, or Down syndrome (DS), is a genetic disorder affecting approximately 1 in 500–750 live births. The prevalence of DS has increased over the past two decades, correlating with a rise in the proportion of pregnancies complicated by advanced ...
