Distinguish between the effects of mutation in somatic and germ-line cells.

Somatic cells:

When normal body cells mutate usually the effects are harmful in different ways which end up killing the cell.

Another type of scenario is where the cells survives but cells from the immune system recognized it and end up killing it.

sometimes somatics cells can accumulate mutations and survive which leads to a tumor or cancer.

Germ-line:

When germ-line cells produce gametes with mutations this mutations can end up killing the embryo. If the embryo survives the mutation can generate all sorts of genetic disorders, the spectrum here is massive and depends on the site of the DNA mutation.
