Dominant radial drusen and Arg345Trp EFEMP1 mutation.
OBJECTIVE
To report a new North American family with dominant radial drusen and Arg345Trp mutation in the EFEMP1 gene.


METHODS
Clinical and molecular genetic family study.


RESULTS
Four family members had macular drusen, and one had submacular fibrosis and visual loss. An Arg345Trp mutation of the EFEMP1 gene was detected in three affected family members, but not in three unaffected members.


CONCLUSIONS
The Arg345Trp mutation remains the only cause of Doyne hereditary macular dystrophy, also known as Malattia Leventinese or radial dominant drusen.
