A Novel Frameshift Mutation Associated with Hurler's Syndrome: A Case Report.


ABSTRACT: Mucopolysaccharidosis 1 (MPS1) is a rare inherited lysosomal storage disorder resulting from the absence or reduction of lysosomal alpha-l-iduronidase due to mutations in the IDUA gene. Three major clinical manifestations have been established including Hurler's or severe type (OMIM 607914), Hurler-Scheie or intermediate type (MIM 607914) and Scheie's or attenuated type (MIM 607016). In the present study, a patient whose disease was diagnosed by biochemical and enzymatic assay was studied in our laboratory. Molecular analysis implemented by PCR-sequencing of all 14 exons and exon-intron junctions confirmed a novel deleterious mutation in a homozygous state. The result of this study has broadened the genotypic spectrum of MPS1 patients, assisting in a more effective approach for carrier testing and counseling.
