Autism in fragile X females.
We present two women with the fragile X syndrome (Martin-Bell syndrome) and autism. Both are mentally retarded, one mildly and one severely. Cytogenetic studies showed a high percentage of lymphocytes with the fragile X chromosome and inactivation occurring preferentially in the normal X chromosome. Autism is shown to be a severe behavioral and cognitive manifestation of the fragile X syndrome ...
متن کاملArousal modulation in females with fragile X or Turner syndrome.
The present study was carried out to examine physiological arousal modulation (heart activity and skin conductance, across baseline and cognitive tasks, in females with fragile X or Turner syndrome and a comparison group of females with neither syndrome. Relative to the comparison group, for whom a greater increase in skin conductance was associated with poor arithmetic performance and less ris...
متن کاملPhysiological arousal in females with fragile X or Turner syndrome.
Physiological arousal was measured in 12- to 22-year-old females with either fragile X, Turner syndrome, or neither disorder to explore potential differences in the manifestation of arousal and anxiety in adolescents and young women. Physiological arousal was measured at baseline and during performance on mental arithmetic, divided attention, and risk-taking tasks. Contrary to prediction, femal...
متن کاملDilemmas in counselling females with the fragile X syndrome.
The dilemmas in counselling a mildly retarded female with the fragile X syndrome and her retarded partner are presented. The fragile X syndrome is an X linked mental retardation disorder that affects males and, often less severely, females. Affected females have an increased risk of having affected offspring. The counselling of this couple was complicated by their impaired comprehension which s...
متن کاملClinical and molecular correlates in fragile X premutation females
The prevalence of the fragile X premutation (55-200 CGG repeats) among the general population is relatively high, but there remains a lack of clear understanding of the links between molecular biomarkers and clinical outcomes. In this study we investigated the correlations between molecular measures (CGG repeat size, FMR1 mRNA, FMRP expression levels, and methylation status at the promoter regi...
