Question 11: 

Question 11 Briefly describe what a retinoblastoma is? (your description should include the cause) Rare malignant tumour of the eye detected in children under 5 years of age Clinical features: white pupil reflex (e.g. to a camera flash) Cause : fault in the repressor gene responsible for inhibiting cell division in retinal cells.
