Retrospective analysis of prenatal diagnosis revealed that LSDs affected 33% (47\/142) of the fetuses. Sandhoff disease (28%), Tay\u2010Sachs disease (27%), and metachromatic leukodystrophy (MLD) (20%) were the most frequent LSDs among the evaluated cases with two false negatives, one each for Tay\u2010Sachs disease and MLD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Enzymatic prenatal diagnoses of certain LSDs may serve as a primary intervention point for families with index cases of infantile or late infantile types of LSDs, since they are associated with poor outcomes, including mortality.
