Heritability curves: a local measure of heritability [PDF]

arXiv, 2020
This paper introduces a new measure of heritability which relaxes the classical assumption that the degree of heritability of a continuous trait can be summarized by a single number.This measure can be used in situations where the trait dependence structure between family members is nonlinear, in which case traditional mixed effects models and ...

Three-dimensional study of grain scale tensile twinning activity in Mg: A combination of microstructure characterization and mechanical modeling [PDF]

arXiv, 2023
Tensile twinning is a main deformation mode in hexagonal close packed structure metals, so it is important to comprehensively understand twinning mechanisms which are not fully disclosed using 2D or small volume 3D characterization techniques. A large area 3D electron backscatter diffraction (EBSD) measurement and crystal plasticity modeling were ...

DNA Methylation and Gene Expression Changes in Monozygotic Twins Discordant for Psoriasis: Identification of Epigenetically Dysregulated Genes

PLoS Genetics, 2012
Monozygotic (MZ) twins do not show complete concordance for many complex diseases; for example, discordance rates for autoimmune diseases are 20%–80%. MZ discordance indicates a role for epigenetic or environmental factors in disease.

Outcome of two pairs of monozygotic twins with pleuropulmonary blastoma: case report

Italian Journal of Pediatrics, 2020
Background Pleuropulmonary blastomas (PPB) are rare aggressive paediatric lung malignancies and are among the most common DICER1-related disorders: it is estimated that 75–80% of children with a PPB have the DICER1 mutation.

Increased expression and altered methylation of HERVWE1 in the human placentas of smaller fetuses from monozygotic, dichorionic, discordant twins. [PDF]

PLoS ONE, 2012
BACKGROUND: The human endogenous retroviral family W, Env(C7), member 1 gene (HERVWE1) is thought to participate in trophoblast cell fusion, and its expression is diminished in the placentas of singleton intrauterine growth-retarded pregnancies. However,

Comparison of brain connectomes using geodesic distance on manifold:a twin study [PDF]

arXiv, 2019
fMRI is a unique non-invasive approach for understanding the functional organization of the human brain, and task-based fMRI promotes identification of functionally relevant brain regions associated with a given task. Here, we use fMRI (using the Poffenberger Paradigm) data collected in mono- and dizygotic twin pairs to propose a novel approach for ...

Maltreatment-associated neurodevelopmental disorders: a co-twin control analysis [PDF]

, 2017
Background: Childhood maltreatment (CM) is strongly associated with psychiatric disorders in childhood and adulthood. Previous findings suggest that the association between CM and psychiatric disorders is partly causal and partly due to familial ...

CDK13‐Related Disorder: Novel Insights From A Series of 27 Cases and Recommendations for Clinical Management

Clinical Genetics, EarlyView.
This report described 27 novel subject with CDK13‐related disorders. Collecting the clinical and radiological data, we better define the phenotypic spectrum of this condition and we suggest a comprehensive clinical management. ABSTRACT In 2016, Sifrim and colleagues described the first group of patients carrying heterozygous pathogenic variants in ...

Trigger Twins: 2 Cases of Ipsilateral Twin Trigger Digit and a Review of Published Literature

Case Reports in Orthopedics, 2019
Background. The aetiology of trigger digits has been debated since Notta first described them in 1850. Aetiology has been segregated for adult and paediatric presentations. While an adult trigger digit is most likely an acquired inflammatory process, the

Automatic Identification of Twin Zygosity in Resting-State Functional MRI [PDF]

arXiv, 2018
A key strength of twin studies arises from the fact that there are two types of twins, monozygotic and dizygotic, that share differing amounts of genetic information. Accurate differentiation of twin types allows efficient inference on genetic influences in a population. However, identification of zygosity is often prone to errors without genotying. In
