In this report, we describe a new mutation located in the coiled 1B domain of desmin and associated with a predominant cardiac involvement and a high degree of cardiac sudden death in a large Indian pedigree with 12 affected members. The index cases was 38-year-old man who presented with progressive difficulty in gripping footwear of 5 years duration with the onset in the left lower limb followed by right lower limb in 6 months. 3 years from onset, he developed lower limb proximal and truncal muscle weakness. There was mild atrophy of the shoulder girdle muscles with grade 3 weakness, moderate wasting of thigh and anterior leg muscles with proximal muscle weakness and foot drop. At 40 years, he had a pacemaker implanted. The 9 exons and intronic boundaries of the desmin gene were sequenced and a heterozygous nucleotide change c. 734A > G in exon 3 was identified.
