Amplifications of NCOA3 gene in colorectal cancers in a Chinese population

Table 1 Comparison of copy number variations of NCOA3 between adjacent normal tissues and healthy normal controls from peripheral blood

Samples		Copy number
	n	Deletion			Amplification		P valuevs HNC
		0	1	2	3	> 3
HNC	152	2	8	135	6	1
ANT	142	3	7	124	5	3	0.776

ANT: Adjacent normal tissues; HNC: Healthy normal controls.
