Incidence and Inheritance
The incidence of dominant optic atrophy has been estimated to be 1:50000 with prevalence as high as 1:10000 in the Danish population (Votruba, 1998). Dominant optic atrophy is inherited in an autosomal dominant manner. That is, a heterozygous patient with the disease has a 50% chance of passing on the disease to offspring, assuming his/her partner does not have the disease. Males and females are affected at the same rate. Although Kjer's has a high penetrance (98%), severity and progression of DOA are extremely variable even within the same family.

Famous quotes containing the words incidence and/or inheritance:
“Hermann Goering, Joachim von Ribbentrop, Albert Speer, Walther Frank, Julius Streicher and Robert Ley did pass under my inspection and interrogation in 1945 but they only proved that National Socialism was a gangster interlude at a rather low order of mental capacity and with a surprisingly high incidence of alcoholism.”
—John Kenneth Galbraith (b. 1908)
“As to honour—you know—it’s a very fine mediaeval inheritance which women never got hold of. It wasn’t theirs.”
—Joseph Conrad (1857–1924)
