Childhood infections and adult height in monozygotic twin pairs.
Adult height is determined by genetics and childhood nutrition, but childhood infections may also play a role. Monozygotic twins are genetically matched and offer an advantage when identifying environmental determinants. In 2005-2007, we examined the association of childhood infections with adult height in 140 height-discordant monozygotic twin pairs from the California Twin Program. To obtain ...
متن کاملEpigenetic influences may explain dental differences in monozygotic twin pairs.
BACKGROUND Comparisons between monozygotic (MZ) co-twins have tended to focus on the similarities between their dentitions rather than differences. The aim of this study was to determine the prevalence of discordant expression for simple hypodontia and supernumerary teeth in MZ twin pairs and to explain how phenotypic differences might occur despite their similar genotypes. METHODS Records of...
متن کاملSerological differences in monozygotic twin pairs discordant for multiple sclerosis.
OBJECTIVES The etiology of MS is unknown but genetic factors are supported by a high concordance in twins. Geographic distribution and migration studies indicate, however, the importance of environmental factors. MATERIAL AND METHODS We studied 3 pairs of genetically identical twins who had shared the same environment but were discordant for MS. Serum samples were assayed for antibodies again...
متن کاملHippocampal MRI volumetry in cognitively discordant monozygotic twin pairs.
OBJECTIVE To investigate whether hippocampal atrophy, a proxy for incipient Alzheimer's disease, can be detected in non-demented monozygotic co-twins of demented twins by using volumetric magnetic resonance imaging (MRI). METHODS Seven pairs of monozygotic female twins discordant for cognitive function (mean (SD) age 75 (4) years), and 10 age and education matched healthy controls (seven wome...
متن کاملDegradation in intrinsic connectivity networks across the Alzheimer's disease spectrum
INTRODUCTION Changes in intrinsic functional connectivity (iFC) have been reported at various stages of the Alzheimer's disease (AD) spectrum. We aimed to investigate such alterations over a variety of large-scale intrinsic brain networks (iBNs) across the spectrum of amyloid β positivity and uncover their relation to cognitive impairment. METHODS Eight iBNs were defined from resting-state fu...
