The 2p24 region has been reported to be associated with NTDs. Here, we report the cases of 2 siblings with trisomy 2p24.3\u2010pter and monosomy 5p14.3\u2010pter caused by the paternal translocation t(2;5)(p24.3;p14.3). Of the two siblings, the elder sister had spina bifida. We determined the nucleotide sequences of the chromosomal breakpoints and found that the sizes of trisomy 2p and monosomy 5p segments were 18.77 and 17.89\u2009Mb, respectively. NTDs were present in four of seven previously reported patients with trisomy 2p and monosomy 5p as well as in one of the two patients examined in the present study. Although the monosomy 5p of the nine patients were similar in size, the two patients reported here had the smallest size of trisomy 2p. When the clinical features of the nine patients were compared to the present two patients, the elder sister had postaxial polydactyly of the left foot in addition to the characteristic facial appearance and spina bifida, indicating that these features were associated with trisomy 2p24.3\u2010pter. To our knowledge, this is the first study on spina bifida to determine the nucleotide sequences of breakpoints for trisomy 2p24.3\u2010pter and monosomy 5p14.3\u2010pter. Increased gene dosages of dosage\u2010sensitive genes or genes at the trisomy segment (2p24.3) of the presented patients could be associated with NTDs of patients with trisomy 2p.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ajmg.a.38313","type":"journal-article","created":{"date-parts":[[2017,6,9]],"date-time":"2017-06-09T16:06:40Z","timestamp":1497024400000},"page":"2201-2209","source":"Crossref","is-referenced-by-count":2,"title":["Clinical and molecular genetic characterization of two siblings with trisomy 2p24.3\u2010pter and monosomy 5p14.3\u2010pter"],"prefix":"10.1002","volume":"173","author":[{"given":"Daisuke","family":"Fukushi","sequence":"first","affiliation":[{"name":"Department of Genetics, Institute for Developmental Research Aichi Human Service Center Kasugai Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenji","family":"Kurosawa","sequence":"additional","affiliation":[{"name":"Division of Medical Genetics Kanagawa Children's Medical Center Yokohama Kanagawa Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuyo","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department of Genetics, Institute for Developmental Research Aichi Human Service Center Kasugai Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaoru","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department of Genetics, Institute for Developmental Research Aichi Human Service Center Kasugai Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenichiro","family":"Yamada","sequence":"additional","affiliation":[{"name":"Department of Genetics, Institute for Developmental Research Aichi Human Service Center Kasugai Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seiji","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Department of Pediatric Neurology Shizuoka Children's Hospital Shizuoka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenji","family":"Yokochi","sequence":"additional","affiliation":[{"name":"Department of Pediatric Neurology Seirei\u2010Mikatahara General Hospital Hamamatsu Shizuoka Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nobuaki","family":"Wakamatsu","sequence":"additional","affiliation":[{"name":"Department of Genetics, Institute for Developmental Research Aichi Human Service Center Kasugai Aichi Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,6,9]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/bdra.23100"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00295832"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199911113412001"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(77)80893-7"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(13)70110-8"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/ca.22654"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199212243272602"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ntt.2004.12.007"},{"key":"e_1_2_7_10_1","first-page":"165","article-title":"Recurrent neural tube defects associated with partial trisomy 2p22\u2010pter: Report of two siblings and review of the literature","volume":"14","author":"Doray B.","year":"2003","journal-title":"Genetic Counseling"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1001\/archpedi.1976.02120120078014"},{"key":"e_1_2_7_12_1","first-page":"269","article-title":"The fetal phenotype in 2p trisomy","volume":"29","author":"Fryns J.
