Forsius-Eriksson syndrome: its relation to the Nettleship-Falls X-linked ocular albinism.

On the basis of clinical data, it had previously been proposed that the Forsius-Eriksson syndrome is identical to Nettleship-Falls X-linked ocular albinism. We performed biopsies of clinically-normal skin in patients with the Forsius-Eriksson syndrome to look for the abnormal melanosomes characteristic of Nettleship-Falls X-linked ocular albinism. There were no abnormalities in the melanosomes of patients with Forsius-Eriksson syndrome. Thus, this syndrome is distinct from the Nettleship-Falls disorder.
