Two molecular genetic projects were undertaken in Drosophila Molecular Genetics in partnership with teachers from High Schools. The students gained experience with DNA extraction through the project and 75% of produce data was usable for research, but the time put in to obtain success was excessive.

The aim was to explore the comorbidity between Angelman syndrome and autism spectrum disorders (ASDs). Identification of autism in children with Angelman syndrome presents a diagnostic challenge. In the present study, 16 children with Angelman syndrome, all with a 15q11-13 deletion, were examined for ASDs. Thirteen children with Angelman syndrome…

This study examined 2 samples of adolescents and mothers using a child-based design (Nonshared Environment in Adolescent Development [NEAD] project, N = 395 families) and a parent-based design (Twin Moms [TM] project, N = 236 twin family pairs) to compare genetic and environmental influences on mothering. For both samples, the same measures of…

The vast amount of biological information that is now available through the completion of the Human Genome Project presents opportunities and challenges. The genomic era has the potential to advance an understanding of human genetic variation and its role in human health and disease. A challenge for genomics research is to understand the…

The difficulties of operationalizing race in research and practice for social, behavioral, and genetic researchers and practitioners are neither new nor related to recent genetic knowledge. For geneticists, the bases for understanding groups are clines, observed traits that gradually change in frequency between geographic regions without distinct…

The cognitive profiles of children with Neurofibromatosis Type 1 (NF-1) have many similarities to those observed in learning disabilities in the general school population, as well as some distinct features. Approximately 30-65 percent of children with NF-1 have learning disabilities; most commonly, they have language and reading disabilities,…

Despite a substantial body of research suggesting genetic influence on educationally relevant behavioural traits, it is not clear how the nature-nurture question is perceived by teachers. In order to answer this question, we surveyed 667 UK primary school teachers, and for comparison also surveyed 1,340 parents about their perceptions of genetic…

Why introduce genetics at primary level? Children are fascinated by themselves and where they come from. Many have heard of genes, mostly through the media coverage of genetics, and want to know more. Children should be engaged in science at an early age to foster an interest and encourage an appreciation of its relevance to life. Genetics sits…

Studies have shown that there is usually a lack of understanding concerning the fields of genetics and genomics among high school students (Lewis and Wood-Robinson, 2000). A recent article (Kirkpatrick et al, 2002) introduced the GAME (Genomics Analogy Model for Educators) model and two of its components: (1) explaining sequencing technology with…

Background: Some previous studies have linked Attention Deficit Hyperactivity Disorder (ADHD) with a bias in spatial awareness away from the left. As genetic research suggests that ADHD may be better viewed as an extreme on a continuum rather than a distinct entity, here we examined this issue in boys from the normal population. Method: From an…

Background: A minority of patients with attention-deficit hyperactivity disorder (ADHD) do not respond favorably to methylphenidate. This has been partially associated with homozygosity for the Dopamine transporter (DAT1) 10-repeat allele and the presence of one or two Dopamine D4 receptor (DRD4) 7-repeat alleles. This study examined the sibling…

Background: The familial nature of obsessive-compulsive disorder (OCD) has been previously demonstrated. The identification of candidate symptoms such as age at onset may help to disentangle the clinical and genetic heterogeneity of the disorder. In this study, the specificity of early-onset OCD was investigated, focusing on the effect of gender,…

Background: A fundamental issue for child psychology concerns the origins of individual differences in early reading development. Method: A measure of word recognition, the Test of Word Reading Efficiency (TOWRE), was administered by telephone to a representative population sample of 3,909 same-sex and opposite-sex pairs of 7-year-old twins.…

Background: Psychopaths are not only antisocial, but also have a callous and unemotional personality profile. This article selectively reviews evidence that psychopathic personality traits are an important factor in understanding and predicting the development of persistent antisocial conduct. Cognitive neuroscience research and more tentative…

Background: Findings from family and twin-based studies of Attention Deficit/Hyperactivity Disorder (ADHD) have indicated that inattentive and combined subtypes cluster together among sibling pairs who both express ADHD symptoms. The current report examines the familial clustering of ADHD subtypes, defined according to latent class and DSM-IV…
