Whole genome views of the mapping signal for six previously known mutations. For each single nucleotide substitution represented on the microarray the difference between the median log2 ratio for probes with N2 and CB4856 sequences is plotted by increasing chromosome number and location from left to right. The mapping signal for each chromosome is shown with data points of different color (red for I, yellow for II, green for III, cyan for IV, blue for V, and magenta for X). The known location of each mutation is (a) chromosome I coordinate 5,432,448 with closest SNP index of 140; (b) chromosome II coordinate 6,712,800 with closest SNP index of 606; (c) chromosome III coordinate 5,107,908 with closest SNP index of 1057; (d) chromosome IV coordinate 12,011,000 with closest SNP index of 1590; (e) chromosome V coordinate 6,512,776 with closest SNP index of 2043; and finally (f) chromosome X coordinate 2,717,348 with closest SNP index of 2629.
