Congenital hypogonadotropic hypogonadism without anosmia 5
Congenital hypogonadotropic hypogonadism without/with anosmia 5 is an autosomal dominant disorder caused by mutations of the CHD7 gene. Sexual maturation is typically disturbed and associated with low levels of gonadotropin and testosterone. Anosmia can be present and makes it difficult to distinguish from Kallmann syndrome then.
