Myelin deficient, a new neurological mutant in the mouse

A new autosomal recessive gene in mice is described that produces deficiencies in central nervous system myelin and quaking or trembling of the hindquarters during locomotion. Although both behavioral and central nervous system abnormalities resembled those produced by qk, the new mutation was not an allele of qk. We propose that the new mutation should be labeled myelin deficient (symbol, mld).
