DLGAP1 and Anxiety: This discrepancy contrasted with the observation of disrupted self-grooming and anxiety-like behavior of mice with knockout of Dlgap3 (Welch et al. 2007), whose variants were significantly associated with OCRD in previous candidate-gene analyses (Bienvenu et al. 2009; Boardman et al. 2011; Crane et al. 2011; Züchner et al. 2009), but less significantly than those of Dlgap1 in the GWAS.
