Myofibrillar Myopathy: Clinico-Genetic Spectrum From a Neuromuscular Center in South India

This is the first study on clinic-genetic features of MFM from India. The various novel phenotypes noted in our cohort include: CRYAB with late symptom onset without cardiac or bulbar involvement, LDB3 with early onset limb girdle syndrome, ptosis and FLNC with distal myopathy and cardiomyopathy and HSPB8 with limb girdle syndrome and ptosis, further expanding the phenotypic spectrum of MFM.
