Background: Disorders of sex development (DSD) due to mutations in the NR5A1 (SF1) gene result in a highly variable phenotype.Objective: To report the clinical phenotype and the molecular/structural characteristics of the gene-protein product arising from three novel mutations of the NR5A1 (SF1) gene found in patients presenting with 46,XY DSD.Method: Phenotype determined from interrogation of clinical case notes. Interpre...

Background: 45,X/46,XY mosaicism is a rare karyotype with a broad phenotypic variation. In patients with a male or predominantly male phenotype, impaired genital development and statural growth have been observed, but little is known about long-term outcomes. Larger multicenter studies are needed.Objective and hypotheses: The aim of this study is to investigate long-term outcomes, namely gonadal function, growth and co-morbidities, in a larger group of m...
