The present study consisted of pilot genorne-wide screen for CNVs in a cohort of 16 patients with early-onset obsessive-compulsive disorder (OCD) and 2 mentally healthy individuals, using array-based comparative enomic hybridization (aCGH) on 44K arrays. A small rare nal inherited microdeletion (-64 kb) was identified in chromosome 15q13.3 of one male patient with very early onset have OCD. The deletion encompassed part of the FA/IN1 gene, which is involved with the glutamatergic system This finding supports the hypothesis of a complex network of several genes expressed in the brain cant ibuting for h genetic risk of OCD, and also supports the glutamatergic involvement in OCD, which has been previsously reported in the literature.6engArtigo10.1371/journal.pone.0110198WOS:000343730400121Acesso abertoWOS000343730400121.pdf2259986546265579
