A family with apparently sex-linked optic atrophy.

Abstract

A family is described in which a probable new form of sex-linked optic atrophy was found in eight individuals. Some additional neurological abnormalities were noted. Results of studies of the Xg blood group excluded close linkage between the optic atrophy and Xg genes. As a probable coincidence, Huntington's chorea was found in a side branch of the family.
