Characterization of genetic variation in the VGLL4 gene in anorexia nervosa

Date Published: 4/14

Abstract: Anorexia nervosa (AN) is a chronic psychiatric disease characterized by a refusal to maintain body weight at or above 85% of that which is normal for height, body dysmorphia, and fear of gaining weight. Genetic studies have had limited success identifying risk loci and a recent genome-wide association study of 1033 AN cases and 3733 controls found no significantly associated loci; however, it identified several genes with single nucleotide polymorphisms (SNPs) of nominal significance: AKAP6, FAM155A, LRP2, NTNG1, VGLL4, and ZNF804B (Wang et al., 2011). We attempted to replicate these associations in an independent cohort of 396 female AN cases of European descent (mean age =32.4 ± 14.25) obtained from the NIMH Center for Collaborative Studies on Mental Disorders (Kaye et al., 2008) and 690 age-matched and education-matched European controls (mean age= 26.34 ± 8.33).
