Col2a1^M2J

This ENU induced mutation is a G-to-A transition at chromosome 15:97,984,776 (GRCm38), which causes a premature stop codon at amino acid 645, and an A-to-T transversion at chromosome 15:97,825,743, in intron 12 that could potentially act as a cryptic splice acceptor site, though RT-PCR did not reveal splicing abnormalities.
