Spinal muscular atrophy: Molecular mechanism of pathogenesis, diagnosis, therapeutics, and clinical trials in the Indian context.

Abstract excerpt

Spinal muscular atrophy (SMA) is a neuromuscular, rare genetic disorder caused due to loss-of-function mutations in the survival motor neuron-1 (SMN1) gene, leading to deficiency of the SMN protein. The severity of the disease phenotype is inversely proportional to the copy number of another gene, SMN2, that differs from SMN1 by a few nucleotides. The current diagnostic methods for SMA include symptom-based...
