Can I apply for a patent by fusing several mutants into one gene?

It is not patentable to fuse several mutants into one gene. Human genes cannot be patented. Human DNA is a natural product and a basic tool for the development of science and technology, and patent protection should not be granted. Synthetic gene products are not subject to this restriction, and hundreds of millions of funds are invested in related research every year. It is necessary to apply for patents for synthetic genetic materials to promote the development of related bio-industries.
