Unilateral calf atrophy secondary to a de novo mutation of the caveolin-3 gene

A 23‐year‐old man was evaluated for atrophy of the left calf. He had a myopathic pattern on electromyography. Light microscopy showed dystrophic changes and reduced immunostaining for dysferlin and caveolin‐3. The subsarcolemmal space was enlarged, and abnormal vesicles were visible with electron mi...

Popis
Shrnutí:	A 23‐year‐old man was evaluated for atrophy of the left calf. He had a myopathic pattern on electromyography. Light microscopy showed dystrophic changes and reduced immunostaining for dysferlin and caveolin‐3. The subsarcolemmal space was enlarged, and abnormal vesicles were visible with electron microscopy. A genetic study showed a heterozygous A45T mutation at exon 2 of the caveolin‐3 gene. Such a mutation has been reported previously with limb‐girdle muscular dystrophy type 1C and rippling muscle disease phenotypes. Muscle Nerve 44: 126–128, 2011.
