MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a helicase superfamily member that binds a specific DNA sequence from the immunoglobulin mu chain switch region. Mutations in this gene lead to spinal muscle atrophy with respiratory distress type 1. [provided by RefSeq, Jul 2008]
PHENOTYPE: Mice homozygous for a spontaneous allele exhibit premature death, progressive limb muscle atrophy, decreased grip strength, severe motor neuron and axonal degeneration, dilated cardiomyopathy, myocardial fiber necrosis, increased heart rate variability, systolic dysfunction and respiratory failure.
