Developmental pathways of children with and without familial risk for dyslexia during the first years of life.
2002
Comparisons of the developmental pathways of the first 5 years of life for children with (N = 107) and without (N = 93) familial risk for dyslexia observed in the Jyvaskyla Longitudinal study of Dyslexia are reviewed. The earliest differences between groups were found at the ages of a few days and at 6 months in brain event-related potential responses to speech sounds and in head-turn responses (at 6 months), conditioned to reflect categorical perception of speech stimuli. The development of vocalization and motor behavior, based on parental report of the time of reaching significant milestones, or the growth of vocabulary (using the MacArthur Communicative Development Inventories) failed t…
Consistencies of psychomotor styles in interpersonal tasks
1975
Abstract.— Interpersonal behaviour of individuals in five tasks (individual performance, two dyadic tasks, two small-group tasks) was videotaped and coded on 11 psychomotor categories concerning (a) movements regulating interaction, (b) indications of tension, and (c) temperamental acts. The individual consistencies were examined on the basis of correlational analyses and task similarities. The consistency of individual psychomotor behaviour across all the tasks was highest in the number of selfinitiated acts (psychomotor activeness). Consistency was also found in the total tension score and the utilization of large/narrow space, while the effect of the particular tasks was clearly demonstr…
Evaluation of proteasomal gene polymorphisms in Lithuanian patients with asthma.
2014
To investigate polymorphisms of proteasomal genes PSMA6 (rs1048990 and rs2277460), PSMC6 (rs2295826 and rs2295827) and PSMA3 (rs2348071) in Lithuanian patients with asthma.One-hundred forty-six asthma patients and 150 control subjects were studied. DNA was extracted from peripheral blood samples. Five single nucleotide polymorphisms (SNP's) of the three proteasomal genes were analyzed using allele-specific amplification or the cleaved amplified polymorphic sequence method.While certain alleles and genotypes of PSMA6 rs2277460 and rs1048990 and PSMA3 rs2348071 SNP's occurred more frequently in asthma patients than in controls, no statistically significant differences in alleles or genotypes …
A comprehensive evaluation of potential lung function associated genes in the SpiroMeta general population sample
2011
Lung function measures are heritable traits that predict population morbidity and mortality and are essential for the diagnosis of chronic obstructive pulmonary disease (COPD). Variations in many genes have been reported to affect these traits, but attempts at replication have provided conflicting results. Recently, we undertook a meta-analysis of Genome Wide Association Study (GWAS) results for lung function measures in 20,288 individuals from the general population (the SpiroMeta consortium). OBJECTIVES: To comprehensively analyse previously reported genetic associations with lung function measures, and to investigate whether single nucleotide polymorphisms (SNPs) in these genomic regions…
Genome-wide significant association of ANKRD55 rs6859219 and multiple sclerosis risk.
2013
Multiple sclerosis (MS) is a genetically complex disease that shares a substantial proportion of risk loci with other autoimmune diseases.1 Along these lines, ANKRD55 , originally implicated in rheumatoid arthritis, was recently reported as a potential novel MS risk gene (rs6859219, p=1.9×10−7).2 Here, we comprehensively validated this effect in independent datasets comprising 8846 newly genotyped subjects from Germany and France as well as 5003 subjects from two genome-wide association studies (GWAS). Upon meta-analysis of all available data (19 686 subjects), ANKRD55 rs6859219 now shows compelling evidence for association with MS at genome-wide significance (OR=1.19, p=3.1×10−11). Our stu…
Opposite Role of Pro-Inflammatory Alleles in Acute Myocardial Infarction and Longevity: Results of Studies Performed in a Sicilian Population
2006
The major trait characterizing offspring in centenarians is a reduction in the prevalence of cardiovascular disease. Because a pro-inflammatory genotype seems to contribute significantly to the risk of coronary heart disease, alleles associated with disease susceptibility would not be included in the genetic background favoring longevity, as suggested by our previous studies on inflammatory cytokines. To confirm whether genotypes of inflammatory molecules play an opposite role in atherosclerosis and longevity, we are studying the role of other proinflammatory alleles, such as pyrin and CCR5, in acute myocardial infarction and longevity. The results support the hypothesis that the genetic ba…
Mutation Analysis Identifies GUCY2D as the Major Gene Responsible for Autosomal Dominant Progressive Cone Degeneration
2008
PURPOSE. Heterozygous mutations in the GUCY2D gene, which encodes the membrane-bound retinal guanylyl cyclase-1 protein (RetGC-1), have been shown to cause autosomal dominant inherited cone degeneration and cone–rod degeneration (adCD, adCRD). The present study was a comprehensive screening of the GUCY2D gene in 27 adCD and adCRD unrelated families of these rare disorders. METHODS. Mutation analysis was performed by direct sequencing as well as PCR and subsequent restriction length polymorphism analysis (PCR/RFLP). Haplotype analysis was performed in selected patients by using microsatellite markers. RESULTS. GUCY2D gene mutations were identified in 11 (40%) of 27 patients, and all mutation…
Missing Evidences in Cancer Genetics: The Retinoblastoma Paradigm
2008
BACKGROUND: Retinoblastoma (Rb) is the most common primary malignant intraocular tumour in childhood. The "two hit" theory, formulated by Knudson in 1971 to explain the variegated clinical expression of the disease, led to the discovery of the so called tumour suppressor genes and the identification of the Rb1 as the prototype of such genes. Mutations of the Rb1 gene are now commonly believed to be the "cause" retinoblastoma, although epidemiological, clinical, and biological evidences argue against it. MATERIAL/METHODS: The Authors have performed a systematic review of available data concerning clinical and diagnostic aspects of retinoblastoma, including molecular genetics. Meta analysis o…
Brief report - "Every little thing gonna be all right" (at least for me): Dispositional optimists display higher optimistic bias for infection during…
2020
Dispositional optimism (DO) and optimistic bias (OB) in risk perception are two distinct phenomena and previous studies about their reciprocal relationship report contrasting results. In the present study, we focused on the relationship between DO and OB when reporting the personal and the other persons' risk about COVID-19. We hypothesized that, when facing a largely uncontrollable risky situation (like the recent pandemic), dispositional optimists would defensively increase their OB about the current risks. A convenience sample of 414 Italian participants aged 18 or older were recruited. They completed a questionnaire investigating past protective behaviors, DO, perceived personal and oth…
Genome-wide association study identifies multiple risk loci for chronic lymphocytic leukemia
2013
Genome-wide association studies (GWAS) have previously identified 13 loci associated with risk of chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL). To identify additional CLL susceptibility loci, we conducted the largest meta-analysis for CLL thus far, including four GWAS with a total of 3,100 individuals with CLL (cases) and 7,667 controls. In the meta-analysis, we identified ten independent associated SNPs in nine new loci at 10q23.31 (ACTA2 or FAS (ACTA2/FAS), P = 1.22 × 10-14), 18q21.33 (BCL2, P = 7.76 × 10-11), 11p15.5 (C11orf21, P = 2.15 × 10 -10), 4q25 (LEF1, P = 4.24 × 10-10), 2q33.1 (CASP10 or CASP8 (CASP10/CASP8), P = 2.50 × 10-9), 9p21.3 (CDKN2B-AS1, P = 1.27 × 10…
