Male and female patients with Kallmann syndrome have either an absent or severely impaired sense of smell. Physical findings associated with hypogonadism include eunuchoidal skeletal proportions. Kallmann syndrome is an inherited condition causing the body to not make enough sex hormones. The KAL1 gene (present on band Xp22.3) encodes anosmin-1, a putative neural cell adhesion molecule that is essential for the migration of olfactory neuron axons toward the olfactory bulb and the establishment of synaptic connections between these axons and the mitral cells present in the olfactory bulb. Kallmann syndrome (KS) is a hereditary disease characterized by congenital hypogonadotropic hypogonadism (CHH) and hyposmia or anosmia. The figure of 50% first cousin marriages among parents of our patients would thus reflect the high consanguinity rate among the population in general. Some patients presenting with X-linked Kallmann syndrome and ichthyosis have a contiguous gene syndrome secondary to large interstitial deletions of Xp22.3 that include at least part of the coding regions of the KAL1 gene and the steroid sulfatase gene.
