Summary
Disorders of Sex Development (DSD) are surprisingly common, however the majority of cases still cannot be explained. Our hypothesis is that a significant proportion of DSD is due to disturbed gene regulation. We will use state of the art methods to analyse the regulation of DSD genes. Our research will improve our knowledge of the regulation of genes that affect DSD and provide a diagnosis for DSD patients for whom the underlying cause is unknown. This in turn will improve clinical management.
Disorders of sex development (DSDs) are surprisingly common, and often result in infertility, genital abnormalities, gender mis-assignment and long-term psychological trauma. This research combines expertise in human molecular genetics, mouse developmental biology and protein chemistry to identify genes important for sex determination and development of the gonads, and discover how they contribute to DSD, in order to improve clinical care to patients with DSD.

Summary
Diseases of the reproductive tract are major health issues. At lease 1 in 100 live births display some sort of gonadal defects. Later in adulthood, one in six couples are affected by infertility, and cancers of the reproductive tract which result in a significant number of deaths each year. This project focuses on understanding the role of the transformation growth factor beta receptor3 (Tgfbr3) in the embryonic and neonatal testis and its impact on adult male reproductive capacities and health.
Defects in sexual development in the human embryo result in some of the most common forms of birth defects, which have profound physiological and psychosexual ramifications for the afflicted individuals. A fuller understanding of the causes of these defects may lead to improved counseling and perhaps also therapeutic possibilities. This project is aimed at finding and studying the genes that control whether an embryo develops as a male or a female, and the genes that are responsible for proper d ....Defects in sexual development in the human embryo result in some of the most common forms of birth defects, which have profound physiological and psychosexual ramifications for the afflicted individuals. A fuller understanding of the causes of these defects may lead to improved counseling and perhaps also therapeutic possibilities. This project is aimed at finding and studying the genes that control whether an embryo develops as a male or a female, and the genes that are responsible for proper development of the gonads, organs that control an individual's sexual development. It is thought that a genetic chain of events is important for gonadal development, and we aim to find the missing links of that chain and to work out how they fit together.Read moreRead less

Summary
Disorders of sexual development are among the most common forms of birth defects in humans (1 in 4,000 births). Many other childhood conditions with this incidence warrant prenatal diagnosis or neonatal screening. These disorders often result in infertility, genital abnormalities and gender mis-assignment. Uncertainty about a child s gender at birth can be very traumatic physically and psychologically for the individual and family concerned. There are profound consequences in later life for the ....Disorders of sexual development are among the most common forms of birth defects in humans (1 in 4,000 births). Many other childhood conditions with this incidence warrant prenatal diagnosis or neonatal screening. These disorders often result in infertility, genital abnormalities and gender mis-assignment. Uncertainty about a child s gender at birth can be very traumatic physically and psychologically for the individual and family concerned. There are profound consequences in later life for the affected individual. The cause of these problems is most often the failure of the delicate network of gene regulation that is responsible for proper development of testes or ovaries in the embryo. This research project will identify genes important for sex determination and development of the gonads, find out how these genes function and interact, and discover how they contribute to cases of aberrant sexual development in humans.Read moreRead less
