From a Family With X-Linked Congenital Nystagmus" [Gutmann et al., 19911. It is correct that in the 1960s and 1970s it was well established that loss of X and Y chromosomes occurred regularly in association with increasing age. Berry and Docherty suggest that the mosaicism in our patient is likely t

β¦ Synopsis
X-linked congenital nystagmus is a rare disorder in which affected males manifest binocular uniplanar nystagmus with associated head oscillation. In the families previously reported, affected females have been described. We report on a multigeneration family with X-linked congenital nystagmus with an affected woman. She was a (46,XX/45,X) mosaic. Magnetic resonance images of the brain of affected individuals were normal.
