Early adaptive immune activation detected in monozygotic twins with prodromal multiple sclerosis.
Journal of Clinical Investigation, 2019 Multiple sclerosis (MS) is a disabling disease of the CNS. Inflammatory features of MS include lymphocyte accumulations in the CNS and cerebrospinal fluid (CSF). The preclinical events leading to established MS are still enigmatic.

Isolated anorectal malformation with rectoperineal fistula in monozygotic twins
Journal of Pediatric Surgery Case Reports, 2019 Incidence of anorectal malformation (ARM) is reportedly 1 in approximately 2500–5000 live births. While its etiology remains elusive, most evidence indicates genetic factors to be the major cause.

Epigenetic supersimilarity of monozygotic twin pairs
Genome Biology, 2018 Background Monozygotic twins have long been studied to estimate heritability and explore epigenetic influences on phenotypic variation. The phenotypic and epigenetic similarities of monozygotic twins have been assumed to be largely due to their genetic ...

DNA methylation signatures of monozygotic twins clinically discordant for multiple sclerosis
Nature Communications, 2019 Multiple sclerosis (MS) is an inflammatory, demyelinating disease of the central nervous system with a modest concordance rate in monozygotic twins, which strongly argues for involvement of epigenetic factors.

Increased DNA methylation variability in rheumatoid arthritis-discordant monozygotic twins
Genome Medicine, 2018 Rheumatoid arthritis is a common autoimmune disorder influenced by both genetic and environmental factors. Epigenome-wide association studies can identify environmentally mediated epigenetic changes such as altered DNA methylation, which may also be ...

Speech characteristics of monozygotic twins and a same-sex sibling: an acoustic case study of coarticulation patterns in read speech [PDF]
, 2003 This case study reports on an acoustic investigation of the motor speech characteristics of a set of young adult male monozygotic (MZ) twins and compares them to those of an age- and sex-matched sibling who participated in the study 2 years later to ...
