BIN1 and centronuclear myopathy: Whilst most of the features of supposedly recessive cases of centronuclear myopathy were reported in genetically unresolved cases, identification of homozygous recessive mutations in the amphiphysin 2 (BIN1) gene in 4 patients form 3 families [59] allows initial genotype-phenotype correlations, although, considering the small number of cases, the range of clinical features associated with mutations in this gene is likely to expand further in the future.
