Choroideremia and hypopituitarism: an association.

Choroideremia is a rare X-linked, progressive, degenerative disease of the retina and choroid. We describe 2 patients, one a female, with choroideremia documented to have hypopituitarism and neurological abnormalities. We hypothesize that this previously undescribed association results from a degenerative process involving tissues of neural origin, or from contiguous submicroscopic gene deletions in the X chromosome region that define choroideremia and possibly hypopituitarism.
