Transcript-Based Diagnosis and Expanded Phenotype of an Intronic Mutation in TPM3 Myopathy.

This study broadens the phenotypic spectrum of recessive TPM3 disease, highlighting tongue fasciculations and bilateral clubfoot, as well as possibly-related cerebral atrophy. It also shows the importance of a broad approach to genetic analysis and the utility of RNA-based studies, demonstrating efficacy of early genome and transcriptome queries in facilitating rapid and cost-effective diagnosis of congenital myopathies.
