Spinal Muscular Atrophy: Indians who need $2.1m drug to fight a rare disease

Affan, seven, and Erhan, five, have Spinal Muscular Atrophy (SMA) – a rare genetic disorder that causes muscle deterioration and affects breathing. Physiotherapy appointments alone cost the family 40,000 rupees ($480; £395) a month, and their sons need constant care as they cannot sit, stand or walk independently.
