Contribution

Metachromatic leukodystrophy, known as MLD, is a devastating genetic disease that progressively destroys the nervous system. Children born apparently healthy lose their ability to walk, talk, see, hear, swallow and then, eventually, breathe. Most do not live to enjoy their fifth birthday. Existing MLD treatment on the NHS is highly effective at halting the disease and is delivered at the Royal Manchester Children’s hospital, but early diagnosis is essential. We already test newborn babies for 10 conditions. Without the need to take any additional blood, MLD screening could be added to each newborn baby’s heel prick test at a cost of 17p per test. Will the Leader of the House ask the Department of Health and Social Care to meet me to discuss this simple and inexpensive solution, which would save the life of a child per month in this country?
