Abstract excerpt
Achromatopsia is an autosomal recessive disorder featuring total colour blindness, photophobia, reduced visual acuity and nystagmus. While mutations in the CNGA3 gene on chromosome 2q11 are responsible for achromatopsia in a subset of patients, previous linkage studies have localized another achromatopsia locus, ACHM3, on chromosome 8q21. Using achromatopsia families in which CNGA3 mutations have been excluded,...
