To identify human genes and understand their roles allows researchers to discover the cause of various diseases.

To contain the meaning of 'by ~ing' or 'while ~ing', can you use 'to infinite' like in the example above?

    Don't use by. Just the gerund clause, with two gerunds. Identifying human genes and understanding their roles allows researchers to discover the cause of various diseases. A gerund is preferred to an infinitive for subject clauses. – John Lawler Sep 12 '18 at 21:52
