Also every mutations has an effect, even if it is very very very small. So truely neutral mutations don't exist.
Nonsense. DNA is a very degenerate code, where the same amino acids can be written in several ways. Glycine for example can be written using codons:
GGA, GGC, GGG or GGU
They all make glycine. So what is the effect of a point mutation changing GGA to GGU?

PS. To provide some appreciation for how degenerate DNA is, it specifies only 20 amino acids, and one stop codon, while providing 64 different codon to specify these.
PPS. Mutations that do not cause a different amino acid to be produced are called "synonymous substitutions" or silent mutations.
