What is MLD?
Metachromatic Leukodystrophy (MLD) is a progressive, genetic, neurometabolic disease that affects the nervous system due to the lack of an enzyme, Ayrlsulfatase-A (ARSA.) Over 300 variants of the ARSA gene on Chromosome 22 are known to cause MLD. 1 in 100 people are carriers of MLD resulting in 1 in 40,000 babies being born with MLD. Of the four types of MLD, late infantile is the most common. While there is now an FDA-approved gene therapy available for pre-symptomatic infantile and early juveniles, Lenmeldy®, access for early-symptomatic cases, older patient cases is much more limited or non-existent.
