We read with great interest the work recently published in Brain (Vissing et al., 2016), in which the findings on limb girdle muscular dystrophy families from the UK, Denmark and Sweden are described. The cases showed a segregation pattern compatible with a dominant transmission. All the affected cases except for one share a heterozygous mutation in the CAPN3 gene previously described in recessive forms of limb girdle muscular dystrophy 2A (LGMD2A) (Richard et al., 1997; Groen et al., 2007).
