Confined Blood Chimerism in Monochorionic Dizygotic Twins Conceived Spontaneously

open access: yesAmerican 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.

Simultaneous cloacogenic carcinoma in dizygotic twins [PDF]

open access: bronzeCancer, 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.

A genome wide linkage scan for dizygotic twinning in 525 families of mothers of dizygotic twins [PDF]

open access: yesHuman 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 ...

Effects of Type of Placentation on Birthweight and its Variability in Monozygotic and Dizygotic Twins [PDF]

open access: bronzeActa geneticae medicae et gemellologiae, 1979
Birthweight was measured on 188 monochorionic monozygotic, 54 dichorionic monozygotic, 102 like-sexed dizygotic, and 94 unlike-sexed dizygotic liveborn twin pairs. Overall, males were found to be significantly heavier than females. These differences were

The Impact of Environmental and Genetic Factors on Bone Quality in Monozygotic and Dizygotic Twins. [PDF]

open access: yesBiomedicines, 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 ...

The control of ovulation in mothers of dizygotic twins. [PDF]

open access: yesThe Journal of Clinical Endocrinology & Metabolism, 1996
Dizygotic twinning is familial, suggesting that there may be an inherited abnormality of the control of ovulation that predisposes to double ovulation and, therefore, dizygotic twins. The present study examines 17 mothers of dizygotic twins (MODZT) and 8 control mothers of singletons by daily blood sampling throughout an entire menstrual cycle.

Rare spontaneous monochorionic dizygotic twins: a case report and a systematic review. [PDF]

open access: yesBMC Pregnancy 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.

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

open access: yesFront Genet, 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 ...
