In all 27 cases the PMD was unilateral, mainly affecting the right side (20\/27), and there were more male (19\/27) than female cases. No familial cases and no parental consanguinity were recorded. A positive correlation was observed between PMD and sex hormone intake and vaginal bleeding in the first trimester of pregnancy. In 12 (1\/49,925) of the 27 PMD cases hypoplasia and\/or syndactyly of the ipsilateral hand was also diagnosed. The index\u2013middle interdigital space was affected in all 11 cases with symbrachydactyly. Additional congenital anomalies were observed in 4\/27 cases, and they were: hemangiomas, hypospadias, and clubfeet. Poland complex (12 cases), isolated PMD (15 cases), and isolated symbrachydactyly (18 cases), showed a similar pattern for symmetry, sidedness, syndactyly type, and sex ratio.<\/jats:p>","DOI":"10.1002\/ajmg.1320040309","type":"journal-article","created":{"date-parts":[[2005,6,11]],"date-time":"2005-06-11T17:32:43Z","timestamp":1118511163000},"page":"263-269","source":"Crossref","is-referenced-by-count":28,"title":["Pectoralis major muscle defect and Poland complex"],"prefix":"10.1002","volume":"4","author":[{"given":"Eduardo E.","family":"Castilla","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joaquin E.","family":"Paz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L\u00eada M.","family":"Orioli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,6,3]]},"reference":[{"issue":"203","key":"e_1_2_1_2_1","first-page":"1","article-title":"Clinical and cytogenetic studies in hypospadias","volume":"59","author":"Aarskog D","year":"1970","journal-title":"Acta Paediatr Scand"},{"key":"e_1_2_1_3_1","first-page":"405","article-title":"Polydactyly: A genetic study in South America","volume":"25","author":"Castilla EE","year":"1973","journal-title":"Am J Hum Genet"},{"key":"e_1_2_1_4_1","first-page":"494","article-title":"Estudio latinoamericano sobre malformaciones congenitas","volume":"76","author":"Castilla EE","year":"1974","journal-title":"Bol OSP\/WHO"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM197209072871004"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1159\/000152560"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0001566000009922"},{"key":"e_1_2_1_8_1","first-page":"127","volume-title":"Birth Defects and Drugs in Pregnancy","author":"Heinonen OP","year":"1977"},{"key":"e_1_2_1_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00445030"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM197410032911403"},{"key":"e_1_2_1_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(75)80390-8"},{"key":"e_1_2_1_12_1","series-title":"Birth Defects: Original Article Series","first-page":"269","volume-title":"Morphogenesis and Malformation of the Limb","author":"Lenz W","year":"1977"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.1320010108"},{"key":"e_1_2_1_14_1","series-title":"Birth Defects: Original Article series","first-page":"37","volume-title":"Morphogenesis and Malformation of the Limb","author":"Milaire J","year":"1977"}],"container-title":["American Journal of Medical Genetics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fajmg.1320040309","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ajmg.1320040309","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,13]],"date-time":"2023-11-13T00:54:21Z","timestamp":1699836861000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ajmg.1320040309"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1979,1]]},"references-count":13,"journal-issue":{"issue":"3","published-print":{"date-parts":[[1979,1]]}},"alternative-id":["10.1002\/ajmg.1320040309"],"URL":"https:\/\/doi.org\/10.1002\/ajmg.1320040309","archive":["Portico"],"relation":{},"ISSN":["0148-7299","1096-8628"],"issn-type":[{"value":"0148-7299","type":"print"},{"value":"1096-8628","type":"electronic"}],"subject":[],"published":{"date-parts":[[1979,1]]}}}
