A repeat expansion in the gene encoding junctophilin-3 is associated with Huntington disease-like 2

Nat Genet. 2001 Dec;29(4):377-8. doi: 10.1038/ng760.

Abstract

We recently described a disorder termed Huntington disease-like 2 (HDL2) that completely segregates with an unidentified CAG/CTG expansion in a large pedigree (W). We now report the cloning of this expansion and its localization to a variably spliced exon of JPH3 (encoding junctophilin-3), a gene involved in the formation of junctional membrane structures.
