An Increased Frequency in HLA Class I Alleles and Haplotypes Suggests Genetic Susceptibility to Influenza A (H1N1) 2009 Pandemic: A Case-Control Study

Figure 3

Allele frequency distribution in general Mexican mestizo population compared to influenza A H1N1/09 patient (INF-P) and contact (INF-C). Statistically significant alleles in the comparison of INF-P to INF-C with available 6-digit allele frequency data for Mexican mestizo population are included. INF-P: influenza patients; INF-C: influenza contacts; HLA: human leukocyte antigen. value < 0.05; value < 0.01. All values were obtained by Fisher exact two-tailed test.
