Description:
We tested the hypothesis that de novo copy number variation (CNV) is associated with autism spectrum disorders (ASDs). We performed comparative genomic hybridization (CGH) on the genomic DNA of patients and unaffected subjects to detect copy number variants not present in their respective parents. Candidate genomic regions were validated by higher-resolution CGH, paternity testing, cytogenetics, fluorescence in situ hybridization, and microsatellite genotyping. Confirmed de novo CNVs were significantly associated with autism (P = 0.0005). Such CNVs were identified in 12 out of 118 (10%) of patients with sporadic autism, in 2 out of 77 (3%) of patients with an affected first-degree relative, and in 2 out of 196 (1%) of controls. Most de novo CNVs were smaller than microscopic resolution. Affected genomic regions were highly heterogeneous and included mutations of single genes. These findings establish de novo germline mutation as a more significant risk factor for ASD than previously recognized.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2993504/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2993504/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sebat, Jonathan -- Lakshmi, B -- Malhotra, Dheeraj -- Troge, Jennifer -- Lese-Martin, Christa -- Walsh, Tom -- Yamrom, Boris -- Yoon, Seungtai -- Krasnitz, Alex -- Kendall, Jude -- Leotta, Anthony -- Pai, Deepa -- Zhang, Ray -- Lee, Yoon-Ha -- Hicks, James -- Spence, Sarah J -- Lee, Annette T -- Puura, Kaija -- Lehtimaki, Terho -- Ledbetter, David -- Gregersen, Peter K -- Bregman, Joel -- Sutcliffe, James S -- Jobanputra, Vaidehi -- Chung, Wendy -- Warburton, Dorothy -- King, Mary-Claire -- Skuse, David -- Geschwind, Daniel H -- Gilliam, T Conrad -- Ye, Kenny -- Wigler, Michael -- MH076431/MH/NIMH NIH HHS/ -- MH61009/MH/NIMH NIH HHS/ -- MH64547/MH/NIMH NIH HHS/ -- R01 MH076431/MH/NIMH NIH HHS/ -- R01 MH076431-01/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2007 Apr 20;316(5823):445-9.
