Assuming the prevalence stated, the overall carrier frequency is between 1: Multiple sulfatase deficiency OMIM The Metacromaticq MR severity scoring method can be used to provide a measure of brain involvement in these individuals [ Eichler et al ] to allow for monitoring disease evolution and response to therapy. The children by the age of five were all in good condition and going to kindergarten when normally by this age, children with the disease can not even speak.

As it progresses, cortical and lducodistrofia atrophy is observed, with ventricular dilatation. Communicates in complete sentences at a quality and performance normal for age.

Current considerations and future perspectives.

MLD is considered a rare disease in the US and other countries. Evidence of myelin recovery and ongoing brain maturation.

Death most commonly results from pneumonia or other infection. Offspring of a proband. Leeucodistrofia and structural analysis of metachromatic leukodystrophy patients in Indian population. Because MLD affects the whole family, management should include a team of professionals to provide genetic counseling and family support through what is often a long disease process.

Initial symptoms are often noted following leucdoistrofia febrile illness or other stress, but it is unclear if a high fever actually accelerates progression.
