Table 2. Association of clinical-pathological characteristics and hypermethylation/LOH status of the WNT7A gene in clear cell RCCs.

Parameters		Methylated	p*-value	LOH
Age	<50	38% (5/13)	0.012	86% (6/7)
	>50	77% (24/31)		85% (17/20)
Fuhrman nuclear grades 1–2		55%(16/29)	0.037	94% (16/17)
Fuhrman nuclear grades 3–4		87%(13/15)		70% (7/10)
Stages I–II		53%(17/32)	0.003	89% (16/18)
Stages III–IV		100%(12/12)		78% (7/9)

^*p-value is referred to correlation between clinical-pathological characteristics and hypermethylation status.
