Condition
Inherited retinal degeneration with progressive loss of photoreceptor cells
Individual at risk
Donor
Guidance at RECRUITMENT/CT/WORK-UP
ACCEPTABLE
Justification for guidance
There is no evidence to support an adverse effect of stem cell mobilisation in donors with RP. Indeed, G-CSF has been shown to increase photoreceptor survival and is even discussed as a novel therapeutic approach:

Any impact of bone marrow collection also seems highly unlikely.
