    Abstract

    Metachromatic leukodystrophy (MLD), the demyelinating disorder resulting from impaired sulfatide catabolism, is caused by allelic mutations of the Arylsulfatase A (ARSA) locus except for extremely rare cases of Saposin-B (Sap-B) deficiency. We characterized twenty-one unrelated Italian patients among which seventeen were due to ARSA activity deficiency and 4 others resulted from Saposin-B defect. Overall, we found 20 different mutant ARSA alleles and 2 different Sap-B alleles. The eleven new ARSA alleles (c.53C>A; c.88G>C; c.372G>A; c.409_411delCCC; c.634G>C; [c.650G>A;c.1108C>T]; c.845A>G; c.906G>C; c.919G>T; c.1102-3C>G; c.1126T>A) were functionally characterized and the novel amino acid changes were also modelled into the three-dimensional structure. The present study is aimed at providing a broader picture of the molecular basis of MLD in the Italian population. It also emphasizes the importance of a comprehensive evaluation in MLD diagnosis including biochemical, enzymatic and molecular investigations.

      • Related Citations
        Calculated set of PubMed citations closely related to the selected article(s) retrieved using a word weight algorithm. Related articles are displayed in ranked order from most to least relevant, with the “linked from” citation displayed first.
      • Gene
        Gene records that cite the current articles. Citations in Gene are added manually by NCBI or imported from outside public resources.
      • Gene (GeneRIF)
        Gene records that have the current articles as Reference into Function citations (GeneRIFs). NLM staff reviewing the literature while indexing MEDLINE add GeneRIFs manually.
      • HomoloGene
        HomoloGene clusters of homologous genes and sequences that cite the current articles. These are references on the Gene and sequence records in the HomoloGene entry.
      • Nucleotide (RefSeq)
        NCBI nucleotide Reference Sequences (RefSeqs) that are cited in the current articles, included in the corresponding Gene Reference into Function, or that include the PubMed articles as references.

        Nucleotide records associated with the current articles through the Gene database. These are the related sequences on the Gene record that are added manually by NCBI.
      • OMIM (calculated)
        Online Mendelian Inheritance in Man (OMIM) records that include the current articles as references in the light bulb links within or in the citations at the end of the OMIM record. The references available through the light bulb link are collected using the PubMed related articles algorithm to identify records with similar terminology to the OMIM record.
