Table 3. Patient distribution by race among the homozygous (C/C, T/T) and heterozygous (T/C) genotypes of the ERCC1 SNP.

	T/T N=15	T/C N=40	C/C N=42	Fisher Exact test, p= 0.0002
Black (%)	0 (0)	9 (24)	28 (76)
White (%)	5 (31)	10 (63)	1 (6)
Hispanic (%)	7 (21)	16 (49)	10 (30)
Asian (%)	0 (0)	2 (67)	1 (33)
Unknown (%)	3 (38)	3 (37)	2 (25)

This table depicts the distribution of ERCC1 rs11615 SNP between the homozygous (C/C, T/T) and heterozygous (T/C) genotypes. Patients are further classified by race. On analyzing this distribution with a Fisher exact test, statistical significance was observed with p=0.00023.
