Mc1r^e-J

This mutation arose spontaneously at the Jackson Laboratory in 1998. It was shown to be an allele of Mc1r by a noncomplementation test with C57BL/6J-Mc1re/J. A single bp deletion at position 856 (NM_008559.2) that results in a frameshift and premature temrination after 10 codons (per. comm. Dr. Ian Jackson).
