Defects in the FILIP1 gene lead to a new form of congenital myopathy associated with facial and cerebral anomalies
An international collaboration reports for the first time the description of five children, from four unrelated consanguineous families, with a pathological bi-allelic variant of the FILIP1 gene. The phenotype combines congenital myopathy with cognitive impairment and facial dysmorphia, and in two cases with cerebral malformations. The FILIP1 gene encodes protein 1, which interacts with filamin … [Read more]

Caveolinopathy: clinical, histological and muscle imaging characteristics and follow-up of a multicentre retrospective cohort
Caveolinopathies are a small group of neuromuscular diseases associated with dysfunction of a family of proteins located in muscle membrane crevices. The most common caveolinopathy is due to a deficiency of caveolin-3 and results in an autosomal dominant muscular dystrophy and a very specific rippling phenomenon (muscle undulations on contraction or percussion of the muscle). … [Read more]
