It is heartening to see KKH undertake this clinical trial in Singapore. One in 150 children in Singapore is reported to have this condition. Favourable results on the efficacy of umbilical cord blood infusion for the treatment of autism will be a huge boon to families in Singapore and a source of great hope to them.
