An investigation of genetic structures underlying autistic traits was performed with samples from twins for which at least one proband had been ascertained as having autism spectrum disorders (ASDs) in our catchment area. In order to adjust for recent concepts of autism, we employed criteria for the broad spectrum of disease and the childhood autism rating(More)
Broad-spectrum autism, referred to as pervasive developmental disorder (PDD), may be associated with genetic factors. We examined 241 siblings in 269 Japanese families with affected children. The sibling incidence of PDD was 10.0% whereas the prevalence of PDD in the general population in the same geographic region was 2.1%. Both of these rates are higher(More)
Although there is accumulating evidence that intelligence quotient (IQ) indexes some aspects of the autistic spectrum disorders (ASDs), the causal relationship between autistic traits and IQ remains controversial. We examined the sources of covariation between autistic traits and IQ. As males have a four times greater risk of ASDs than females,(More)
Adenosine is a physiologically active molecule produced locally in many sites of the body to regulate various cell functions. Measurement of levels of the factor in organs and biological fluids provides clues to its role and we reported an accurate quantitative high-performance liquid chromatography method for urinary adenosine requiring no preliminary(More)
This study identified the individual differences in the effects of Japanese Dyslexia. The participants consisted of 12 Japanese children who had difficulties in reading and writing Japanese and were suspected of having developmental disorders. A test battery was created on the basis of the characteristics of the Japanese language to examine Kana’s(More)
BACKGROUND The characteristics of epilepsy in patients with Kabuki syndrome with KMT2D mutations (KABUK1) have not yet been well documented. This is the first review to explore this. MATERIALS & METHODS We enrolled 14 patients with KABUK1, whose median age was 13.6years (range=4.1-21.3years). Their medical records from October 1981 to May 2016 were(More)
There are conflicting hypotheses for the causes of Dyslexia in reading and writing difficulties, such as the phonological deficit hypothesis, double deficit hypothesis, magnocellular deficits hypothesis etc. The cause of the difficulties may vary between individuals. Moreover, most of these hypotheses consider only a single disability, despite the fact that(More)
