Limb girdle muscular dystrophy 2H is a rare autosomal recessive muscular dystrophy, clinically highly variable, caused by mutations in the TRIM32 gene. Here we describe a 35-years-old who experienced progressive muscle weakness. The muscle biopsy revealed an unspecific pattern of atrophic and hypertrophic fibers; the immunohistochemistry for several proteins was normal. Comparative genomic hybridization (CGH) analysis showed a heterozygous deletion of the entire TRIM32 gene. On the other allele we identified the R316X nonsense mutation. The genetic diagnosis of LGMD2H in this case was reached by using a novel high throughput diagnostic tool. (C) 2013 Elsevier B.V. All rights reserved.
