Cytogenetic studies have implicated large chromosomal aberrations in the etiology of approximately 5\u20137% of autism patients, and the recent advent of array\u2010based techniques allows the exploration of submicroscopic copy number variations (CNVs). We genotyped a 14\u2010year\u2010old boy with autism, spherocytosis and other physical dysmorphia, his parents, and two non\u2010autistic siblings with the Illumina Human 1M Beadchip as part of a study of the molecular genetics of autism and determined copy number variants using the PennCNV algorithm. We identified and validated a de novo 1.5\u2009Mb microdeletion of 14q23.2\u201023.3 in our autistic patient. This region contains 15 genes, including spectrin beta (<jats:italic>SPTB<\/jats:italic>), encoding a cytoskeletal protein previously associated with spherocytosis, methylenetetrahydrofolate dehydrogenase 1 (<jats:italic>MTHFD1<\/jats:italic>), a folate metabolizing enzyme previously associated with bipoloar disorder and schizophrenia, pleckstrin homology domain\u2010containing family G member 3 (<jats:italic>PLEKHG3<\/jats:italic>), a guanide nucleotide exchange enriched in the brain, and churchill domain containing protein 1 (<jats:italic>CHURC1<\/jats:italic>), homologs of which regulate neuronal development in model organisms. While a similar deletion has previously been reported in a family with spherocytosis, severe learning disabilities, and mild mental retardation, this is the first implication of chr14q23.2\u201023.3 in the etiology of autism and points to <jats:italic>MTHFD1<\/jats:italic>, <jats:italic>PLEKHG3<\/jats:italic>, and <jats:italic>CHURC1<\/jats:italic> as potential candidate genes contributing to autism risk. <jats:bold><jats:italic>Autism Res<\/jats:italic><\/jats:bold> <jats:italic>2011,4:221\u2013227<\/jats:italic>. \u00a9 2011 International Society for Autism Research, Wiley Periodicals, Inc.<\/jats:p>","DOI":"10.1002\/aur.186","type":"journal-article","created":{"date-parts":[[2011,3,1]],"date-time":"2011-03-01T21:27:35Z","timestamp":1299014855000},"page":"221-227","source":"Crossref","is-referenced-by-count":28,"title":["A de novo 1.5\u2009Mb microdeletion on chromosome 14q23.2\u201023.3 in a patient with autism and spherocytosis"],"prefix":"10.1002","volume":"4","author":[{"given":"Anthony J.","family":"Griswold","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deqiong","family":"Ma","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephanie J.","family":"Sacharow","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joycelyn L.","family":"Robinson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James M.","family":"Jaworski","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harry H.","family":"Wright","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruth K.","family":"Abramson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helle","family":"Lyb\u00e6k","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nina","family":"\u00d8yen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael L.","family":"Cuccaro","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John R.","family":"Gilbert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Margaret A.","family":"Pericak\u2010Vance","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2011,2,28]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/13810"},{"key":"e_1_2_6_3_1","unstructured":"Autism Genetics Resource Exchange.
