long thanh » long han, long trinh, truong thanh
yang yang » wang yang, wang yan
liang wei » xiang wei, zhang wei, wang wei
wong laid » wong lai, kong land

• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yang liang wei gene ((long thanh) OR (luong thanh)) wong laid ;*".
