Homozygosity mapping performed in a consanguineous Faroese family revealed a 3.5 MB homozygous region on chromosome 10q22.2-q22.3 (chr10:77,233,812-80,685,953; GRCh37) that segregated with the disease in the family. Analysis of 3 other unrelated patients, including 2 sisters, revealed homozygosity in an overlapping region (Gronskov K et al. 2013).
Clinical featuresThis section has been translated automatically.
Clinically, most affected individuals were characterized by pale complexion with a tendency to lighter skin coloration than their unaffected relatives; ocular symptoms predominated, with nystagmus and iris transillumination present in all patients. Pigmentation of the peripheral fundus was extremely sparse. Visual evoked potentials showed crossed asymmetry of the cortical visual response (misdirection) in all subjects studied. Photophobia was not a major problem. Hair color varied from pale blond to dark brown (Gronskov K et al. 2013).
