Fetal and Postnatal Growth in Turner Syndrome and their Associations with the Dosage Effects of the X-Linked Gene: a Cross-Sectional Data Base Analysis of the French National Rare Disease Network

Background: Shox gene, located on the short arm (p) of the X chromosome, is expressed in the growth plate cartilage in pre and post natal life. Whereas the dose dependent association between the number of active copies of the SHOX gene and height is well established, studies addressing a more subtle variability between the quality of fetal growth, the severity of post natal height deficit and karyotype subgroups in Turner syndrome (TS) are still limited....

X Chromosome Gene Dosage and the Risk of Developing Congenital and Acquired Traits in Turner Syndrome: a Cross-Sectional Database Analysis of the French National Rare Disease Network

Background: The broad spectrum of associated diseases underlying the diverse phenotypes of patients with Turner syndrome (TS) has been extensively described. However, the underlying pathophysiological mechanisms remain unknown. Few studies have analyzed congenital and acquired diseases as a function of karyotype, and conflicting results have been obtained, calling into question the role of haploinsufficiency for genes located on the X chromosome.Objectiv...
