For many years it was believed the brothers, who both have macrocephaly, were affected by nonsyndromic X\u2010linked mental retardation. This was because, apart from absent speech and intellectual disability, the phenotype of the two men was not characteristic of Angelman syndrome. Conversely, the cousin, in addition to severe intellectual disability, language impairment, and ataxic gait, has microcephaly. None of the three have seizures, and so in the presence of the brothers' macrocephaly, Angelman syndrome was not considered until a diagnosis was made in the younger distant cousin. We report on a familial imprinting center deletion and the importance of considering the mild and atypical Angelman syndrome phenotypes within the differential diagnosis of intellectual handicap, particularly in clarifying the genetic risk to other family members. \u00a9 2007 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ajmg.a.31952","type":"journal-article","created":{"date-parts":[[2007,11,1]],"date-time":"2007-11-01T18:47:59Z","timestamp":1193942879000},"page":"78-82","source":"Crossref","is-referenced-by-count":8,"title":["Atypical Angelman syndrome with macrocephaly due to a familial imprinting center deletion"],"prefix":"10.1002","volume":"146A","author":[{"given":"Anne","family":"Ronan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karin","family":"Buiting","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tracy","family":"Dudding","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,12,19]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.2004.021923"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.1320510109"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/ng0495-395"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1086\/301935"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s004390051160"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1086\/367926"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.40.2.87"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ejhg.5200362"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1086\/302473"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.38.12.834"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1093\/hmg\/ddh296"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1136\/jmg.34.5.426"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ejhg.5201264"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.1316"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.31074"},{"key":"e_1_2_7_17_1","doi-asserted-by":"crossref","first-page":"94","DOI":"10.1159\/000484740","article-title":"A single\u2010tube PCR test for the diagnosis of Angelman and Prader\u2010Willi syndrome based on allelic methylation differences at the SNRPN locus","volume":"5","author":"Zeschnigk M","year":"1997","journal-title":"Eur J Hum Genet"}],"container-title":["American Journal of Medical Genetics Part A"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fajmg.a.31952","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ajmg.a.31952","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,18]],"date-time":"2023-10-18T09:10:38Z","timestamp":1697620238000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ajmg.a.31952"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,12,19]]},"references-count":16,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2008,1]]}},"alternative-id":["10.1002\/ajmg.a.31952"],"URL":"https:\/\/doi.org\/10.1002\/ajmg.a.31952","archive":["Portico"],"relation":{},"ISSN":["1552-4825","1552-4833"],"issn-type":[{"value":"1552-4825","type":"print"},{"value":"1552-4833","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,12,19]]}}}
