Handedness in twins: meta-analyses
Background In the general population, 10.6% of people favor their left hand over the right for motor tasks. Previous research suggests higher prevalence of atypical (left-, mixed-, or non-right-) handedness in (i) twins compared to singletons, and in (ii)

No evidence of a higher 10 year period prevalence of diabetes among 77,885 twins compared with 215,264 singletons from the Danish birth cohorts 1910-1989 [PDF]
AIMS/HYPOTHESIS: Previous Danish twin studies have found a highly increased risk of precursors of type 2 diabetes as well as a higher prevalence of type 2 diabetes among twins compared with singletons.

Confined Blood Chimerism in Monochorionic Dizygotic Twins Conceived Spontaneously
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.

Protease inhibitor (Pi) locus, fertility and twinning [PDF]
In a sample of 160 Dutch twin pairs and their parents, we found that mothers of dizygotic twins had frequencies of the S and Z alleles at the protease inhibitor (Pi) locus that were 3 times higher than a control sample.

A Twin Study of Genetic Contributions to Hippocampal Morphology in Schizophrenia
Our goal was to establish whether altered hippocampal morphology represents a trait marker for genetic vulnerability in schizophrenia. We outlined the hippocampi on high-resolution MR images obtained from matched samples of control and discordant ...

Discordant phenotypes in twins with infantile nystagmus
Infantile nystagmus (IN) may result from aetiologies including albinism and FRMD7 mutations. IN has low prevalence, and twins with IN are rare. Whilst discordant presentation has been previously reported for IN, we present for the first time the ...

Molar incisor hypomineralisation: current knowledge and practice
Background Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected ...

Risk of psychiatric disorders among the surviving twins after a co-twin loss
Losing a co-twin by death is a severely stressful event yet with unknown impact on the surviving twin’s risk of psychiatric disorders. We identified all Swedish-born twins who lost a co-twin by death between 1973 and 2013 (n = 4,528), their 4939 non-twin

Epigenetic discrimination of Lebanese monozygotic and dizygotic twins: Summarized notes in a single paper [PDF]
Monozygotic twins’ differentiation is worldwide limited due to the fact that they share the same genotype. For forensic purposes, many studies involving monozygotic twins were accomplished.

Associations between birth size and later height from infancy through adulthood : an individual based pooled analysis of 28 twin cohorts participating in the CODATwins project [PDF]
Background: There is evidence that birth size is positively associated with height in later life, but it remains unclear whether this is explained by genetic factors or the intrauterine environment.
