What: Rare genetic disorder affecting the development of the hypothalamus and sense of smell
How does it present: Failure to start puberty, lack of small, in males they have undescended testes, infertility, decreased muscle mass, osteoporosis
What is the cause: Mutation in genes responsible for development of the hypothalamus which then alters the release of GnRH which is used to stimulate the production of sex hormones
