Is Doyne honeycomb retinal dystrophy inherited ?
How is Doyne honeycomb retinal dystrophy inherited? Doyne honeycomb retinal dystrophy (DHRD) is inherited in an autosomal dominant manner. This means that having only one changed (mutated) copy of the responsible gene in each cell is enough to cause signs and symptoms of the condition.  When a person with an autosomal dominant condition has children, each child has a 50% (1 in 2) risk to inherit the mutated gene from the affected parent. Children who do not inherit the mutated gene will not develop or pass on the disease.
