I have a qqplot of my whole genome sequencing data; A plot is for showing possibly significant driver genes. I tried to read about qqplot though but people only say about the skewedness while I want to know from these two genes which one are more likely to be driver
You also seem to ignore other genes that deviate more of your null hypothesis. I recommend to plot the histogram of the p-values to see if the distribution is uniform
This looks to be a pretty good Q-Q plot. My recollection of doing Q-Q plots is that a good Q-Q requires a "more or less" linear relationship for the model to be considered okay. Again this model looks good, its 1:1, albeit it does deviate a little (for the gene of interest). TP15 falls outside the 1:1.
@Devon Ryan states TP15 has good biological credentials, which is clearly important. It maybe worth checking MAP15 because this is "more or less" within your model (for my Q-Q plots definitely within the model :-) ).
In summary, its just my opinion - that on the basis of the Q-Q plot the driver is the not the expected candidate.
