A comparative study of mPCR, MLPA, and muscle biopsy results in a cohort of children with Duchenne muscular dystrophy: A first study

Abstract

This is the first study from India and possibly in English literature, comparing the sensitivity and pattern of mutations by both mPCR and MLPA in the same cohort of DMD. It further validates that 36.4% of MLPA-negative cases were confirmed to have DMD by IHC. The clinical accuracy has been very high in our cohort. MLPA-negative samples should be subjected for next-generation sequencing before contemplating a biopsy.
