Table 1.

Mutual exclusivity of HLA class I-related genes Log odds ratio shows how strongly presence or absence of alterations in gene A are related with presence or absence of alterations in gene B. Log odds ratio of more than 0 corresponds association towards co-occurrence, equals to or less than 0 corresponds mutual exclusivity; p < 0,05 is significant association.

geneA	geneB	p-Value	Log Odds Ratio	Association
B2M	HLA-B	0.005	−2.359	Tendency towards mutual exclusivity (Significant)
HLA-A	HLA-B	<0,001	2.876	Tendency towards co-occurance (Significant)
HLA-A	HLA-C	<0,001	>3	Tendency towards co-occurance (Significant)
HLA-B	HLA-C	0.002	2.457	Tendency towards co-occurance (Significant)
