Similarly increased congenital anomaly rates after intrauterine insemination and IVF technologies: a retrospective cohort study
2012
International audience; BACKGROUND: While intrauterine insemination (IUI), a simple, inexpensive and non-invasive technique, is the most used assisted reproduction technology (ART) worldwide, the risk of major birth defects following IUI is paradoxically not well documented. METHODS: Retrospective cohort study performed in Burgundy, France, over a 9-year period which consisted of the cross analysis of two prospective databases, the Burgundy perinatal network database and the database of the assisted conception units in Burgundy. A total of 1348 ART singletons [in vitro fertilization technologies (IVFT): n= 903; IUI: n= 445] matched with 4044 infants conceived naturally, 552 ART twins (IVFT:…
Phenotypic spectrum and genomics of undiagnosed arthrogryposis multiplex congenital
2022
BackgroundArthrogryposis multiplex congenita (AMC) is characterised by congenital joint contractures in two or more body areas. AMC exhibits wide phenotypic and genetic heterogeneity. Our goals were to improve the genetic diagnosis rates of AMC, to evaluate the added value of whole exome sequencing (WES) compared with targeted exome sequencing (TES) and to identify new genes in 315 unrelated undiagnosed AMC families.MethodsSeveral genomic approaches were used including genetic mapping of disease loci in multiplex or consanguineous families, TES then WES. Sanger sequencing was performed to identify or validate variants.ResultsWe achieved disease gene identification in 52.7% of AMC index pati…
Occurrence of oro-facial malformations in a tertiary center hospital of Southern Italy: retrospective study on ten thousand newborns
2015
Congenital anomalies (CA) are one of the major cause of infant mortality and childhood morbitity, affecting 2-3% of all babies. Approximately 1% of these newborns have syndromes or multiple anomalies; Cranio-facial anomalies are often a component part of these pathologies. Several newborns with cranio-facial anomalies are affected by syndromes composed of multiple malformations thought to be etiologically and/ or pathogenetically related. One of the most frequent sign of these syndromes is the cleft lip and/or cleft palate. It is estimated that 30% of cleft cases are syndromic and conversely, therefore, approximately 70% are non-syndromic. Oral clefts are among the most widely known and com…
