Figure 3. Sequence analysis of Rom1. The position of the point mutation is indicated by red arrowheads on sequence chromatograms from the Control DBF1 mouse (top) and the M-1156 mouse (bottom). A T→C single base substitution at position 1,195 of Rom1 (M96760, National Center for Biotechnology Information [NCBI]) was identified in the M-1156 mouse line.
