Perhaps you should try some spelling variations:
hua gene » human gene, a gene, hua ren
yang jui » yang judy, yang xi, yang yi
wong sam » wong sau, kong sar, von sam
yan tan » tan tan, yan clan, yan guan
tan hua » tuan hua, wang hua, tan chia
won sau » wong sau, wong siu
wang » wing, wan, lang
lai » laid

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan tan hua gene ((yang jui) OR (yang di)) ((won sau) OR (((wong sam) OR (wong lai)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan tan hua gene ((yang jui) or (yang di)) ((won sau) or (((wong sam) OR (wong lai)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan tan hua gene ((yang jui) or (yang di)) ((won sau) or (((wong sam) OR (wong lai)))) ;*.
