In standard genetics, we often think of an allele as a variation of a gene that would result in a difference in a physical manifestation of that gene. In a paternity test, samples from the mother, the child, and the suspected father would be analyzed in the same manner.

De novo mutations may explain genetic disorders in which an affected child has a mutation in every cell in the body but the parents do not, and there is no family history of the disorder. These genetic changes are not present in a parent’s egg or sperm cells, or in the fertilized egg, but happen a bit later when the embryo includes several cells.

It is possible that the normal function of this gene is to transport the sweet-smelling chemical into the cells from which it is released into the air, or maybe it is required for the development of those cells in the first place.
