The existence of such a syndrome has recently been dismissed based on a new understanding of the ichthyoses. We report on the clinical history of a 14-year-old boy with congenital ichthyosis, small stature, hypogonadism, facial dysmorphism, nystagmus, kypho-scoliosis and myogenic dystrophy. He was diagnosed as Rud syndrome but developed neither seizures nor mental retardation. However a cousin was mentally retarded. The ichthyosis was familial as five relatives had ichthyosis but no other features of Rud syndrome. The patient had a deletion of the steroid-sulfatase gene. He had neither chondrodysplasia punctata, nor Kallmann syndrome, two conditions which are part of the contiguous gene syndrome of the Xp22.3 region. Most case reports previously reported as Rud syndrome can now be reassigned under a contemporary ichthyosis classification that does not include Rud syndrome as a distinct entity. This case was clearly distinct from Refsum disease, Sjögren-Larsson syndrome and any of the other ichthyosis disorders that have been suggested as a replacement for Rud syndrome. Thus the case reported here appears distinct from any previously described, currently recognized syndrome.</p>","PeriodicalId":7908,"journal":{"name":"Annales de genetique","volume":"42 1","pages":"45-50"},"PeriodicalIF":0.0,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21084886","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}

After cytogenetic detection and confirmation by fluorescence-in-situ hybridization we performed short tandem repeat typing in a child with i(9p), three with i(12p) and three with i(18p). The extra chromosomes were monocentric in each case, the i(9p) and i(12p) constitutions were found in mosaic with normal cell lines. Our results and those of other groups indicate a strong role of maternal meiosis in isochromosome formation: in one i(8p), 4 out of 5 i(9p), 7 out of 12 i(12p) and 18 out of 23 i(18p) families a maternal meiotic nondisjunction had occurred prior to the centromere misdivision. For chromosome 18, the majority of isochromosomes originated from a maternal meiosis II error (16/18). For the other tetrasomic constitutions the isochromosomes could be delineated from paternal as well as from maternal origin, the short tandem repeat typing patterns being consistent with meiotic or mitotic cell stages of formation. Thus, independently of the chromosomal origin, in the majority of cases with additional euchromatic isochromosomes maternal meiosis nondisjunction is the initial step followed by centromeric misdivision. Postzygotic nondisjunction as suggested previously due to mosaics observed in tetrasomies 9p and 12p seems to be of minor importance. The observed origin of isochromosomes 18 corresponds to that of trisomy 18, where the majority of cases can be delineated from maternal meiosis II errors.</p>","PeriodicalId":7908,"journal":{"name":"Annales de genetique","volume":"42 2","pages":"75-80"},"PeriodicalIF":0.0,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21300160","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}
