Bioinformatic analysis identifies mitochondrial biogenesis including synthesis of glutamate/gamma-aminobutyric acid as a potential transcriptional target of HDAC4<sup>A778T</sup> activity relevant to the behavioral deficits identified in this new mouse model of disordered eating.
Body image satisfaction was measured using Stunkard's silhouettes, and the 26-item Eating Attitudes questionnaire (EAT-26) was used to evaluate participants' risk of disordered eating.
Cross-sectional data from adolescents (n = 2,271; 52% females) of White (23%), Black (34%), Hispanic (20%), and Asian (23%; 82% Hmong) ethnicity/race participating in the EAT 2010 study were used to examine associations between overweight status and disordered eating behaviors across ethnic/racial groups.
Data from a longitudinal sample of female twins were selected: measures of risk for DE from Wave 1 (N = 699, 351 pairs, aged 12-15 years), and the Eating Disorder Examination (EDE) and Children's Anxiety Sensitivity Index (CASI) from Wave 2 (N = 669, 338 pairs, aged 16-19 years).

If replicated in a larger sample, these results may have important clinical implications, including potential for the use of MC4R agonists in the treatment of obesity and disordered eating.
Larger replication studies are needed to further elucidate the role of the COMT Val(108/158)Met polymorphism in the regulation of disordered eating behaviour.
More students with overweight and obesity scored above the established EAT-26 cut off value indicating at risk of disordered eating compared to students who were at a normal weight or underweight (52.1% vs. 38.8%, respectively, X<sup>2</sup> (1) =16.1, p < .001).
Our findings identify SF1 neurons as a key part of the neurocircuitry that controls both feeding and related affective states, giving potential insights into the relationship between disordered eating and stress-associated psychological disorders in humans.
P-adiponectin at follow-up correlates to eating disorder symptom severity in patients without morbid obesity, indicating that P-adiponectin should be further investigated as a possible potential prognostic biomarker for BN.
Seven studies were identified by the systematic review, with complete data sets of five community (n = 1750, 64.5% female) and two clinical (n = 426, 100% female) samples combined to perform four secondary-data analyses: 5-HTTLPR x Traumatic Life Events to predict ED status (n = 909), 5-HTTLPR x Sexual and Physical Abuse to predict bulimic symptoms (n = 1097), 5-HTTLPR x Depression to predict bulimic symptoms (n = 1256), and 5-HTTLPR x Impulsiveness to predict disordered eating (n = 1149).
Since genetic factors likely contribute to the biological vulnerability to bulimia nervosa (BN) and binge eating disorder (BED), we investigated whether the functional 196G/A single nucleotide polymorphism (SNP) of the BDNF gene was associated to BN and/or BED or to some phenotypic aspects of the disordered eating.
The dopamine D4 receptor (DRD4), a well-characterized, polymorphic gene, is an attractive candidate for contributing risk to disordered eating and anorexia nervosa (AN).
The insulin-like growth factor 2 (IGF2) and the arginine vasopressin 1a receptor (AVPR1a), previously shown to be associated with disordered eating, were also associated with CAPS scores.
The current results implicate the following genes: CLEC5A, LOC136242, TSHZ1, and SYTL5 for the AN spectrum phenotype; NT5C1B for the BN spectrum phenotype; and ATP8A2 for the disordered eating behaviors phenotype.

The current study examined the psychometric properties of the Intuitive Eating Scale-2 (IES-2) in a Hispanic American sample of adult college students (N=482), and related IES-2 scores to levels of disordered eating, body mass index (BMI), fruit and vegetable consumption, and body shape satisfaction.
The insulin-like growth factor 2 (IGF2) and the arginine vasopressin 1a receptor (AVPR1a), previously shown to be associated with disordered eating, were also associated with CAPS scores.

These findings suggest that the C(-1019)G polymorphism in the 5-HT1A receptor gene is associated with disordered eating symptoms in Korean female adolescents.
This study suggests that utilizing polymorphisms in and near SLC6A4, including 5-HTTLPR, may not be useful in identifying genetic risk factors for disordered eating.
