Dental treatment of twin monozygotic brothers with Fragile X syndrome
Fragile X syndrome (FXS) is the main cause of inherited mental retardation and is the result of transcriptional silencing of the fragile X mental retardation gene FMR1. An absence of the associated protein FMRP leads to the deregulation of many genes, which results in phenotypes of Attention-Deficit Hyperactivity Disorder (ADHD), anxiety, epilepsy and autism. The aim of this article is to repor...
متن کاملMonozygotic twin brothers with the fragile X syndrome: different CGG repeats and different mental capacities.
Little is known about the mechanism of CGG instability and the time frame of instability early in embryonic development in the fragile X syndrome. Discordant monozygotic twin brothers with the fragile X syndrome could give us insight into the time frame of the instability. We describe monochorionic diamniotic twin brothers with the fragile X syndrome who had different CGG repeats and different ...
متن کاملTranscriptome Analysis of Monozygotic Twin Brothers with Childhood Primary Myelofibrosis
Primary myelofibrosis (PMF) is a chronic myeloproliferative disorder in human bone marrow. Over 50% of patients with myelofibrosis have mutations in JAK2, MPL, or CALR. However, these mutations are rarely detected in children, suggesting a difference in the pathogenesis of childhood PMF. In this study, we investigated the response to drug treatment of a monozygotic twin pair with typical childh...
متن کاملTwin sisters, monozygotic with the fragile X mutation, but with a different phenotype.
The absence of the fragile X mental retardation protein (FMRP) results in fragile X syndrome. All males with a full mutation in the FMR1 gene and an inactive FMR1 gene are mentally retarded while 60% of the females with a full mutation are affected. Here we describe monozygotic twin sisters who both have a full mutation in their FMR1 gene, one of whom is normal while the other is affected. Usin...
متن کامل45,X Turner's syndrome in monozygotic twin sisters.
A 7-year-old girl was admitted to the hospital for anaemia, secondary to intestinal blood los (melaena). She was found to have 45,X Turner's syndrome. Her identical twin sister also had Turner's syndrome with a 45,X chromosome complement. According to various criteria the probability of monozygosity was 0.9905. Although the incidence of twinning is greater than usual in families of patients wit...
