TL;DR
Findings support previous research indicating significant genetic and non-shared environmental influences on AN syndromes.
Abstract
BACKGROUND: Genetic and environmental influences on broadly-defined anorexia nervosa (AN) syndrome were examined in a population-based twin sample. METHODS: AN syndrome was assessed in 672 female 17 year-old twins using structured interviews and a self-report questionnaire. RESULTS: Twenty-six probands with AN syndrome were identified. Biometrical model-fitting analyses indicated that genetic and non-shared environmental factors accounted for 74% and 26% of the variance in AN syndrome, respectively. CONCLUSIONS: Findings support previous research indicating significant genetic and non-shared environmental influences on AN syndromes.

Relatives of anorexic and bulimic probands had increased risk of clinically subthreshold forms of an eating disorder, major depressive disorder, and obsessive-compulsive disorder and obsessional personality traits may be a specific familial risk factor for anorexia nervosa.

It is hypothesized that genetic liability for this variant of substance-use disorder is reflected in a spectrum of risk indicators linked to the inability or unwillingness to inhibit behavioral impulses, including conduct, oppositional defiant, and attention-deficit disorder in children and antisocial personality disorder and behavior in adults.

Both anorexia nervosa and bulimia nervosa are familial, and the observation that familial aggregation and cross-transmission extend to milder phenotypes suggests the validity of their inclusion in a continuum of familial liability.

In the absence of genotype-environment interactions, distributional skewness and mean-variance regression in DZ twins are found to be more powerful tests of directional dominance than the standard model fitting procedure and these tests may be worthwhile in future studies.

Both the pattern of comorbidity and the relationship to epidemiologic risk factors suggested an etiologic continuity between narrowly and broadly defined anorexic syndromes, which support the hypothesis of a spectrum of anoreXic-like Syndromes in women.

Analysis of data from the Eating Disorders Questionnaire (EDI) given to the twins and data as to weight loss, length of amenorrhoea and other characteristics of anorexia nervosa, together with the twin and family data, supports the hypothesis that genetic factors are very significant in the aetiology of anoresis.

The relative strengths and weaknesses of the pairwise and probandwise rates are reviewed and it is shown that Torrey's conclusion that the monozygotic twin concordance for schizophrenia is weaker than what is widely accepted is based upon his incorrect use of pairwise rates.
