Correlations between binary molecular markers.

Correlations between pairs of all binary molecular markers and corresponding statistical significance values. In each cell, the top entry gives the phi coefficient between the corresponding two markers. The phi coefficient is a measure of association for two binary variables and equals the Pearson correlation coefficient in this case. The bottom entry (in brackets) gives the p-value of Fisher's exact test for the corresponding two markers, where a small value indicates a significant association. Only two pairs are significantly correlated, namely X1p36 and X9p (correlation 0.263, p-value 0.0134) and X1p36 and X22q (correlation 0.358 and p-value 0.0005). All other correlations are smaller than 0.13.
