The major malformations described most frequently are those common in the general population: congenital heart defects, cleft lip and/or cleft palate, and genitourinary abnormalities. There is an even greater birth prevalence of major malformations in children born to women taking two antiepileptic drugs, and the prevalence of major malformations continues to increase with each additional antiepileptic drug taken during pregnancy. Microcephaly or growth retardation may be observed, particularly when there has been exposure to multiple antiepileptic drugs. A characteristic pattern of minor anomalies may be observed, including midface and digital hypoplasia, and there is an increased incidence of hemorrhagic disease of the newborn in children exposed to phenytoin, carbamazepine, and phenobarbital., We discuss the evaluation and management of children exposed to antiepileptic drugs in utero. \u0000 \u0000 \u0000Keywords: \u0000 \u0000fetal anticonvulsant syndrome; \u0000anticonvulsant embryopathy; \u0000fetal hydantoin syndrome; \u0000fetal valproate syndrome; \u0000carbamazepine embryopathy","PeriodicalId":142022,"journal":{"name":"Cassidy and Allanson's Management of Genetic Syndromes","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126993785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is characterized by mucocutaneous telangiectases, recurrent epistaxes, gastrointestinal bleeding, and arteriovenous malformations in the lungs, brain, and liver. Hereditary hemorrhagic telangiectasia can be caused by mutations in either the endoglin gene or the ALK1 gene, both of which encode proteins involved in serine-threonine kinase signaling in the endothelial cell. These genes are thought to account for the majority of cases. Currently, the diagnosis is made using published clinical diagnostic criteria. Affected younger adults may be presymptomatic, so mutation analysis, where available, is an important adjunct to clinical diagnosis. \u0000 \u0000 \u0000Keywords: \u0000 \u0000hereditary hemorrhagic telangiectasia; \u0000epistaxis; \u0000pulmonary arteriovenous malformation; \u0000brain arteriovenous malformation; \u0000hepatic arteriovenous malformation; \u0000embolization; \u0000serine-threonine kinase signaling; \u0000endothelium; \u0000endoglin; \u0000ALK1","PeriodicalId":142022,"journal":{"name":"Cassidy and Allanson's Management of Genetic Syndromes","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133687512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Together, their combined prevalence in live-born infants approaches 1 in 4000 births. These syndromes are unique among chromosome disorders as well as the other conditions described in this text since about 90% of children with trisomies 18 and 13 die before their first birthday. Because of this high infant mortality rate, the conditions are sometimes labeled simplistically as “lethal.” However, about 10% of infants do indeed survive. Regardless of the figures for survival, the parents of the child and the practitioners caring for the family seek an approach to management and health supervision as in any other serious medical disorder. Ongoing support and care by professionals are crucial to a family whose child has an uncertain prognosis. This chapter will provide a concise review of the literature of the syndromes and a plan of management for the primary care of children with trisomies 18 and 13. \u0000 \u0000 \u0000Keywords: \u0000 \u0000trisomy 19; \u0000trisomy 13; \u0000Edwards syndrome; \u0000Patau syndrome; \u0000poor survival; \u0000multiple congenital anomalies","PeriodicalId":142022,"journal":{"name":"Cassidy and Allanson's Management of Genetic Syndromes","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128655262","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many cases have been identified worldwide from a diversity of ethnic groups. The diagnosis is based on the clinical recognition of a unique and complex pattern of physical, developmental, and behavioral features, many of which are subtle in early childhood, becoming more distinctive with advancing age. There is a characteristic craniofacial appearance with rather close-set, deep-set eyes under heavy brows, a square jaw, and an unusual full, everted upper lip. Speech delay with or without hearing loss is common. Ocular abnormalities are frequently found and short stature with failure to thrive is often seen. There are variable levels of intellectual handicap and the neurobehavioral phenotype includes sleep disturbance with an inverted circadian rhythm of melatonin, self-injurious behaviors, stereotypies, and sensory integration disorders. \u0000 \u0000 \u0000Keywords: \u0000 \u0000Smith-Magenis syndrome; \u0000microdeletion; \u0000interstitial deletion of chromosome 17p11.2; \u0000intellectual handicap; \u0000short stature; \u0000craniofacial dysmorphism; \u0000behavioral phenotype; \u0000self-injurious behavior; \u0000stereotypies","PeriodicalId":142022,"journal":{"name":"Cassidy and Allanson's Management of Genetic Syndromes","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132811876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
