Background. Prevalence of childhood anxiety disorders at specific ages and genetic etiological influences on anxiety disorders in young children have been little studied. The present study reports prevalence estimates in a community sample of 6-year-old twins, and patterns of genetic and environmental influences on these early-onset anxiety disorders. Method. Using a two-phase design 4662 twin-pairs were sampled and 854 pairs were assessed in the second phase by maternal-informant diagnostic… 

Obsessive–compulsive disorder, tics and anxiety in 6-year-old twins

Heritability of OCD and familial aggregation of OCD, tics and anxiety disorders were investigated in a community sample of 6-year-old twins and the findings are consistent with the hypotheses of a tic-related early-onset OCD phenotype, but also with the hypothesis of an anxiety-relatedEarly-onsets OCD phenotype.

The Common Genetic Architecture of Anxiety Disorders

This represents the largest genetic study of anxiety to date-however larger sample sizes will be required to further examine the common genetic architecture underlying anxiety.

A Multivariate Genetic Analysis of Specific Phobia, Separation Anxiety and Social Phobia in Early Childhood

Familial influences, especially shared environment, are central to the comorbidity between Specific Phobia and both Separation Anxiety and Social Phobia.

The role of genetic and environmental factors in covariation between anxiety and anger in childhood

It is demonstrated that anger, assessed by CBCL items, is heritable in children at a similar rate to prior studies, and the majority of etiological influences on anxiety and anger are independent of each other.

Phenotypic and genetic differentiation of anxiety‐related behaviors in middle childhood

The current results suggest that ARBs can be differentiated both phenotypically and genetically within middle childhood, with subtypes reflecting symptom groupings of diagnosable disorders but also aspects of temperament.

Normative childhood repetitive routines and obsessive compulsive symptomatology in 6-year-old twins.

The moderate correlation between normative childhood repetitive routines and obsessive compulsive symptomatology, attributable to genetic factors, is consistent with the hypothesis that high levels of this trait in young children constitute a risk factor for the development of obsessiveCompulsive symptoms.

While adult studies find somewhat distinct etiological differences between anxiety and phobic disorders, the current results suggest that their relative genetic and environmental influences are not as clearly demarcated in children.

The Genetic Basis of Child and Adolescent Anxiety

Genetic and Environmental Influences on Child Reports of Manifest Anxiety and Symptoms of Separation Anxiety and Overanxious Disorders: A Community-Based Twin Study

Genetic and environmental influences in the determination of individual differences in self-reported symptoms of separation anxiety (SAD), overanxious disorder (OAD), and manifest anxiety (MANX) were evaluated in children and adolescents, finding that additive genetic and environmental effects could be set equal across age and gender for these variables.

The Virginia Twin Study of Adolescent Behavioral Development. Influences of age, sex, and impairment on rates of disorder.

The prevalence rates and patterns of findings from this study of twins are consistent with those of other epidemiological studies, supporting previous findings of few differences in rates of psychiatric disorder between twins and singletons.

Genetics and developmental psychopathology: 2. The main effects of genes and environment on behavioral problems in the Virginia Twin Study of Adolescent Behavioral Development.

A widespread influence of genetic factors on risk to adolescent psychopathology is supported and suggests that the contribution of different types of social influence may vary consistently across domains of measurement.

Genetic and Environmental Influences on Separation Anxiety Disorder Symptoms and Their Moderation by Age and Sex

Using DeFries and Fulker's multiple regression analysis, it is found that genetic and shared environmental influences both contributed appreciably to variation in SAD symptoms and were significantly moderated by both sex and age.

A review and meta-analysis of the genetic epidemiology of anxiety disorders.

Meta-analyses of data from family and twin studies of panic disorder, generalized anxiety disorder, phobias, and obsessive-compulsive disorder revealed significant familial aggregation, underscoring the importance of identifying putative environmental risk factors that predispose individuals to anxiety.

Behavioral genetic analyses of self-reported anxiety at 7 years of age.

Certain symptoms of self-reported anxiety in children 7 years of age seem to result, at least in part, from genetic factors, including physiological and social anxiety symptoms that appear to be genetically influenced.

Prevalence of psychiatric diagnoses and the role of perceived impairment: findings from an adolescent community sample.

The inclusion of an impairment criterion had a significant impact in reducing the prevalence rates of overall psychiatric disorders, mainly through impairment's effects on internalizing disorders, specifically anxiety-based disorders (i.e., simple and social phobia).

A population-based twin study of major depression in women. The impact of varying definitions of illness.

Nine commonly used definitions of major depression, which produced life-time prevalence rates ranging from 12% to 33%, were examined and the results of model fitting to twin correlations suggested that the liability to depression results from genetic factors and environmental experiences unique to the individual.

A genetic study of maternal and paternal ratings of problem behaviors in 3-year-old twins.

Significant sex differences in genetic and environmental influences and evidence for sibling contrast effects were found for the Overactive scale and shared environmental influences were important for Total Problems and somewhat larger for Externalizing than for Internalizing behaviors.

Twins early development study (TEDS): a multivariate, longitudinal genetic investigation of language, cognition and behavior problems in childhood.

A result that suggests that general impairment may be a better target for genetic research than specific language impairment independent of nonverbal cognitive problems is found, and DNA has been obtained so far for more than 4000 pairs is being used initially in molecular genetic studies of language problems and hyperactivity.
