Mutation of the ITPR1 gene (inositol 1,4,5-triphosphate receptor, type 1) has been identified recently as the underlying cause, and in most cases the molecular defect is a multiexon deletion. To date, 5 different SCA15 families have been identified with ITPR1 gene deletion.<\/jats:p>\n               <jats:p>Methods: We have designed a synthetic, dual-color multiplex ligation-dependent probe amplification (MLPA) assay that measures copy number with high precision in selected exons across the entire length of ITPR1 and the proximal region of the neighboring gene, SUMF1 (sulfatase modifying factor 1). We screened 189 idiopathic ataxic patients with this MLPA assay.<\/jats:p>\n               <jats:p>Results: We identified ITPR1 deletion of exons 1\u201310 in the previously reported AUS1 family (4 members) and deletion of exons 1\u201338 in a new family (2 members). In addition to the multiexon deletions, apparent single-exon deletions identified in 2 other patients were subsequently shown to be due to single-nucleotide changes at the ligation sites.<\/jats:p>\n               <jats:p>Conclusions: The frequency of ITPR1 deletions is 2.7% in known familial cases. This finding suggests that SCA15 is one of the \u201cless common\u201d SCAs. Although the deletions in the 5 families identified worldwide thus far have been of differing sizes, all share deletion of exons 1\u201310. This region may be important, both in terms of the underlying pathogenetic mechanism and as a pragmatic target for an accurate, robust, and cost-effective diagnostic analysis.<\/jats:p>","DOI":"10.1373\/clinchem.2009.124958","type":"journal-article","created":{"date-parts":[[2009,5,8]],"date-time":"2009-05-08T01:28:06Z","timestamp":1241746086000},"page":"1415-1418","source":"Crossref","is-referenced-by-count":36,"title":["Development
