Distal spinal muscular atrophy (DSMA, OMIM #182960),1 also known as distal hereditary motor neuronopathy (DHMN),2 Charcot-Marie-Tooth (CMT) spinal type,3 and neuronal motor neuropathy of peroneal muscular atrophy4,5 include a heterogeneous group of disorders. The primary defect responsible for these conditions lies in the lower motor neurone, with distal involvement of only lower or both lower and upper limbs.
DSMA is genetically heterogeneous. Four autosomal dominant and three autosomal recessive forms of the disease have already been mapped, including the Jerash type DHMN and congenital DSMA (table 1
). However, the responsible genes were identified for only two of them: the glycil tRNA synthetase gene for DSMA type 56 and the immunoglobolin µ-binding protein 2 gene (IGHMBP2) for DSMA type 6.7
