TABLE 2.

Allele and Genotype Distribution of the SDF1-3′G > A SNP in 257 HIV-1–Infected Cases vs. 113 HIV-1–Seronegative Controls From the Xhosa Population

SNP	HIV+ (%) (n = 257)	HIV− (%) (n = 113)	Pvalue*
SDF1-3′G > A
G	495 (96.3)	224 (99.1)	0.0319
A	19 (3.7)	2 (0.9)
GG	239 (93)	111 (98.2)	0.1191
GA	17 (6.6)	2 (1.8)
AA	1 (0.4)	0
	PHWE = 0.26	PHWE = 0.92

^*Two-sided Fisher’s exact or χ². P < 0.05 was required for statistical significance and is presented in bold.

Number of alleles, HIV+ (2n = 514) and HIV− (2n = 226).

HIV+ indicates HIV-1 seropositive; HIV−, HIV-1 seronegative; HWE, Hardy–Weinberg equilibrium.
