Comparison of quantitative PCR and microarray measurements of gene expression differences between populations
| Gene | qPCR E/A | Microarray E/A |
|---|---|---|
| Cyp6g1 | 3.26 (P = 0.0008) | 2.12 (P < 0.0001) |
| CG9509 | 0.99 (P = 0.003) | 1.21 (P < 0.0001) |
| CG7214 | -2.61 (P = 0.002) | -2.42 (P < 0.0001) |
| CG7203 | -1.57 (P = 0.005) | -2.41 (P < 0.0001) |
| Nap1 | -0.46 (P = 0.02) | 0.03 (P = 0.35) |
| CG15295 | 0.26 (P = 0.60) | 0.14 (P = 0.17) |
Values represent the log2 of the mean fold-change difference in expression between the European (E) and African (A) populations as determined by qPCR or microarray. P-values for the qPCR were determined by Mann-Whitney U tests, and P-values for the microarray experiment were determined by BAGEL.
