Summary
The purpose of this study is to explore the genetic basis of reproductive disorders and cleft lip and/or palate.
Description
The World Health Organization estimates approximately 10% of couples experience some sort of infertility problem.
In humans, puberty is the process through which we develop reproductive capacity.
The timing of puberty varies greatly in the general population and is influenced by both genetic and environmental factors. In extreme cases of pubertal delay, puberty progresses only partially or not at all and results in the clinical picture of congenital hypogonadotropic hypogonadism (CHH), either accompanied by anosmia in 50% of cases (Kallmann syndrome [KS]) or by normal sense of smell (nCHH), with a male: female ratio of 4:1.
CHH is due to GnRH deficiency (incidence 1: 4,000-10,000) and result in the failure of sexual maturation and infertility. It is genetically heterogeneous, with multiple patterns of inheritance and several associated loci. In the clinical spectrum of GnRH deficiency, CHH may also be associated with a cleft lip/palate (CL/P) in 5 to 7% of cases. However, this prevalence increases up to 40% in CHH patients carrying a mutation in a CL/P gene, suggesting a genetic overlap between CHH and CL/P.
Disorders of puberty have provided insight into the biology of reproduction and genetic technologies have enabled us to deepen understanding in this field. The focus of this study is to better understand the genetic control of puberty and human reproduction as well as its link with CL/P.
Increasing understanding of the molecular basis (genes) of inherited reproductive disorders and CL/P may enable investigators to:
- improve diagnostic testing and treatments for these problems
- develop new diagnostic tests and therapies for patients
- enhance counseling for patients and families with reproductive disorders
- enhance counseling for patients and families with cleft lip/palate
