X-linked congenital nystagmus: a problem in genetic counseling
Annals of Ophthalmology
|April 1, 1976
Abstract:
A pedigree with X-linked congenital nystagmus is presented. A mother wished information about prenatal sex determination. The large number of clinically affected female heterozygotes in the pedigree illustrates a potential problem in genetic counseling for this condition and possibly other X-linked disorders which affect the eye.
