Distinct datasets collect genetic and clinical information on SMA, CMT, familial amyloidosis of TTR-type, muscle glycogenoses, spinal and bulbar muscular atrophy, congenital myopathies, and muscular dystrophies (congenital, limb girdle, and facio-scapulo-humeral dystrophy types). This evidence concerns the gene TTR and congenital myopathy with cores.
