The presence of obsessions and compulsions similar to OCD in autism, the identification of this region in a genome-wide linkage analysis of individuals with autism spectrum disorders (ASDs), and the hypothesized role of glutamate in ASDs make SLC1A1 a candidate gene for ASD as well. To test for association between SLC1A1 and autism, we typed three single nucleotide polymorphisms (SNPs, rs301430, rs301979, rs301434) previously associated with OCD in 86 strictly defined trios with autism. Family-Based Association Tests (FBAT) with additive and recessive models were used to check for association. Additionally, an rs301430-rs301979 haplotype identified for OCD was investigated. FBAT revealed nominally significant association between autism and one SNP under a recessive model. The G allele of rs301979 was undertransmitted (equivalent to overtransmission of the C allele under a dominant model) to individuals with autism (Z=-2.47, P=0.01). The G allele was also undertransmitted in the T-G haplotype under the recessive model (Z=-2.41, P=0.02). Both findings were also observed in the male-only sample. However, they did not withstand correction for multiple comparisons.

The Obsessive Compulsive Scale of the Child Behavior Checklist predicts obsessive-compulsive disorder: a receiver operating characteristic curve analysis / James J. HUDZIAK in Journal of Child Psychology and Psychiatry, 47-2 (February 2006)

Methods: A receiver operating characteristic (ROC) curve analysis was applied to data from 61 patients with clinically determined OCD, 64 clinical controls and 73 general population controls to determine the best sum score on the CBCL-OCS to predict confirmed OCD in children. Using the ROC-determined cutoff, this score was applied to a national sample of CBCL data from 2460 singleton children ages 4–18 and to 20,016 children ages 7–18 from three large general population twin samples to determine the estimated prevalence in the general population. Results: Using a CBCL-OCS score of 5 demonstrated an area under the curve (AUC) of .88 with high sensitivity (92%) and moderate specificity (67%) compared to clinical controls. Compared to the general population controls, the AUC was .96 with high sensitivity (92%) and specificity (89%). In the twin samples, the number of participants with CBCL-OCS scores above this cutpoint was 2.3–7.1%. Conclusions: These findings suggest that the OCS of the CBCL may provide a highly effective way to screen for childhood OCD, and that the prevalence of childhood OCD may have been underestimated, thus prompting the need for further research into screening children for this condition.
