Loss of function or null (in the case of complete loss) is the term used for the mutation in a gene that often results in a reduction of the product of that gene.

A mutation is a change or modification in the nucleotide sequence of an organism's genome that may change the genetic message carried by the gene.

Loss of function or null mutation:

It is a mutation that leads to the loss of the function of the protein produced by the mutated gene.
It may reduce the protein function of the produced by mutated gene as well
The recessive gene mutation causes such mutation.

Thus, the correct term for such mutation is - loss of function or null (in the case of complete loss)
