Abstrakt: Distal spinal-muscular atrophy 1 (DSMA1) or spinal-muscular atrophy with respiratory distress type 1 (SMARD1) is a rare neuromuscular disorder resulting from IGHMBP2 mutations. It is an autosomal recessive disease. We present the case of a 1-year-old girl admitted for respiratory failure associated with pneumonia. Right hemidiaphragmic elevation on the chest radiograph and distal retractions suggested the diagnosis of DSMA1. It was confirmed by muscle biopsy and molecular analysis. This unrecognized diagnosis should be considered when respiratory failure develops in the first year of life and is associated with diaphragmatic paralysis and distal muscle atrophy. Electromyography with measurement of nerve conduction velocity and muscle biopsy suggest the diagnosis, which must be confirmed by genetic analysis. After identifying the mutations, it is possible to perform prenatal diagnosis.
