A pathomechanism similar to that observed in DM1 was also proposed for myotonic dystrophy type 2 (dystrophia myotonica 2, DM2, OMIM: 602668), a disease caused by an expansion of CCTG repeats in the first intron of the CCHC-type zinc finger nucleic acid binding protein gene (Liquori et al., 2001). This evidence concerns the gene CNBP and myotonic dystrophy type 2.
