ABSTRACT
Caveolins are essential proteins in caveolae architecture, small plasma membrane invaginations that play a key role in a variety of cellular processes, including vesicular trafficking and signal transduction. Mutations in the gene encoding caveolin-3 (CAV3) cause a broad spectrum of clinical phenotypes, ranging from isolated hyperCKemia to most severe limb girdle muscular dystrophy and cardiomyopathy. We report a novel heterozygous p.Val44Met (c.130G > A) CAV3 mutation in two brothers presenting with persistent elevation of serum creatine kinase, myalgia and hypercholesterolemia. Immunofluorescence study with anticaveolin-3 antibodies on muscle biopsy of the proband confirmed a reduced immuno-reactivity of caveolin-3 on the sarcolemma. This findings support the pathogenic effect of this novel mutation and extend the genotypic and clinical spectrum of Caveolinopathies. Finally, we discuss the hypothesis that the association between CAV3 mutations and hypercholesterolemia may not be coincidental.
