Health Agenda

Hawton’s and van Heeringen’s seminar on suicide is a rich source of current knowledge on the topic and highly useful for generalists. However, genetic risk factors for suicide are underappreciated in the seminar. Although family history of suicide is mentioned as important and genetic loading is listed under distal risk factors, their close connection is not emphasised: familial clustering of suicide is partly due to genetic risk factors. Convergent evidence towards this end has emerged from distinctly different genetically informative research designs. Appropriate consideration of these insights is an important public health agenda and matters for mental health literacy, as international surveys suggest disbelief in the genetics of suicide is widespread among medical and psychology undergraduates and in the general population.

Keratoconus is a progressive thinning and anterior protrusion of the cornea that results in steepening and distortion of the cornea, altered refractive powers, and reduced vision. Keratoconus has a complex multifactorial etiology, with environmental, behavioral, and multiple genetic components contributing to the disease pathophysiology. Using genome-wide and candidate gene approaches several genomic loci and genes have been identified that highlight the complex molecular etiology of this disease. The review focuses on current knowledge of these genetic risk factors associated with keratoconus.

BackgroundTo clarify the role of genetic and environmental factors in criminal behavior (CB), we examined all CB and violent and non-violent subtypes (VCB and NVCB, respectively) in a Swedish national sample of adoptees and their relatives.MethodCB was defined by a conviction in the Swedish Crime Register with standard definitions for VCB and NVCB subtypes. We examined adoptees born 1950–1991 (n = 18 070) and their biological (n = 79 206) and adoptive (n = 47 311) relatives.ResultsThe risk for all CB was significantly elevated in the adopted-away offspring of biological parents of which at least one had CB [odds ratio (OR) 1.5, 95% confidence interval (CI) 1.4–1.6] and in the biological full and half-siblings of CB adoptees (OR 1.4, 95% CI 1.2–1.6 and OR 1.3, 95% CI 1.2–1.3, respectively). A genetic risk index (including biological parental/sibling history of CB and alcohol abuse) and an environmental risk index (including adoptive parental and sibling CB and a history of adoptive parental divorce, death, and medical illness) both strongly predicted probability of CB. These genetic and environmental risk indices acted additively on adoptee risk for CB. Moderate specificity was seen in the transmission of genetic risk for VCB and NVCB between biological parents and siblings and adoptees.ConclusionsCB is etiologically complex and influenced by a range of genetic risk factors including a specific liability to CB and a vulnerability to broader externalizing behaviors, and by features of the adoptive environment including parental CB, divorce and death. Genetic risk factors for VCB and NVCB may be at least partially distinct.

Objective: To identify genetic risk factors and frequency and to describe congenital defects of the fetus. Methods: The research was conducted at the Genetic Research Institute of the Faculty of Medicine. University of Zulia. Maracaibo. We studied patients who attend to the prenatal genetic clinic. According to the Genetic risk factors Identified, it indicated different prenatal diagnostic procedures: fetal echography, fetal echocardiography, triple maternal serum marker, amniocentesis for fetal karyotype and molecular analysis. Results: We included 568 patients. 79.05% of the total showed only one genetic risk factor and the 20.95% two or more. The advanced maternal age was the most frequent genetic risk factor found (40.85%), followed by first-degree family history with a congenital defect (35.21%), abnormal fetal echography (13.73%), exposure to teratogenic agents (10.39%), history of recurrent abortion (7.04%), history of fetal death (4.22%), consanguinity (1.93%), and history of neonatal death (1.76%). They were diagnosed 101 fetuses with congenital defects, one balanced translocation, two fetal deaths and 26 spontaneous abortions. Conclusion: The genetic risk factors identification, served as a starting point to indicate prenatal diagnostic procedures allowed a health evaluation of the fetus and adequate genetic counseling. Key words: Prenatal diagnosis, Risk factors, Genetic counseling.

Background. It is not known if a subject's characteristic level of self-rated depression symptoms index their genetic or environmental liability to major depressive disorder when measurement error and other occasion-specific influences are taken into account.Method. Monozygotic (N = 408) and dizygotic (N = 295) adult female twin pairs from a population-based registry were surveyed twice with an average follow-up interval of 61 months. At each occasion subjects completed a structured clinical interview (SCID) to assess lifetime history of major depression and the subject-rated Symptom Check List (SCL) to assess current level of depressive symptomatology. A bivariate measurement model was used to estimate the genetic and environmental correlations between liability to reliably diagnosed lifetime history of major depression and the characteristic or temporally stable SCL depression score.Results. The genetic and non-familial environmental correlation between liability to reliably diagnosed major depression and the characteristic level of SCL depression symptoms (and the proportion of variance shared between measures) is +0·70 and +0·24 respectively.Conclusions. When allowance is made for diagnostic unreliability and temporal fluctuations in the level of subject-rated symptoms, 70% of the variance in genetic risk factors and 24% of the variance in environmental risk factors is shared by a diagnosis of lifetime major depression and total SCL depression symptom score. SCL depression scores may therefore be a useful screening measure for many of the genetic risk factors which influence liability to major depression.

Background: Keratoconus is characterized as a bilateral, progressive, non-inflammatory thinning of the cornea resulting in blurred vision due to irregular astigmatism. Keratoconus has a multifactorial etiology, with multiple genetic and environmental components contributing to the disease pathophysiology. Several genomic loci and genes have been identified that highlight the complex molecular etiology of this disease. Conclusion: The review focuses on current knowledge of these genetic risk factors associated with keratoconus.
