Upregulation of Soluble HLA-G in Chronic Left Ventricular Systolic Dysfunction

Table 4

Distribution of haplotypes of the 14 bp insertion/deletion polymorphism (Del/Ins) and the +3142 SNP (C/G) in the 3′-untranslated region of the HLA-G gene in relation to left ventricular ejection fraction.

Ejection fraction	DelC/DelC	DelC/DelG	DelC/InsC	DelC/InsG	DelG/DelG	DelG/InsG	InsG/InsG	Total
>40%	62 (31.2%)	15 (7.5%)	1 (0.5%)	74 (37.2%)	1 (0.5%)	8 (4.0%)	38 (19.1%)	199 (100.0%)
<40%	20 (32.8%)	4 (6.6%)	0 (0.0%)	23 (37.7%)	0 (0.0%)	9 (14.8%)	5 (8.2%)	61 (100.0%)

  (Chi-Square test, 10.50, df = 4), for the Chi-Square test DelC/InsG was added to the DelC/DelC group and DelG/DelG was added to the DelG/InsG group.
