    The mutants are small with impaired hind limb movement, i.e. 'hot-foot' like behavior (of one or both limbs), and show agouti dilute coat color. These mice are fragile and usually die by or before 5 weeks of age; a colony needs to be maintained through ovarian transplants. Complementation tests between heterozygous NMF244 and DLS/LeJ mice produced six affected mice in a total of 22 progeny, suggesting that NMF244 represents a new allele of dilute-lethal in the Myo5a gene. These affected mice show a more severe phenotype than NMF244, i.e. they intermittently lean to the side, fall over, but are able to regain their walking position; they also show a non-agouti grey coat color. The coat color appears to result from a non-agouti grey allele that is known to exist in heterozygotes for the dilute-lethal allele of Myo5a, and becomes apparent in the presence of the agouti dilute allele, carried by the female NMF244. Standard pathology work-up on three mutants (23 - 29 days of age) revealed no abnormalities



These mice carry an ENU-induced mutation that is characterized by agouti dilute coat color, impaired hind limb movement, and instability.
