The OR7D4 gene encodes a particular olfactory receptor, a protein that reacts to specific molecules in the nose to trigger a signal in our perception of smell. OR7D4 encodes one of hundreds of different types of olfactory receptors in the nose. A mammalian pheromone called androstenone — and other chemicals similar to it — trigger the receptor encoded by OR7D4.
People normally have two alleles per gene, one inherited from their mother and one inherited from their father.
This allele has been widespread globally for tens of thousands of years.
Also known as: RT.
This allele originates from an ancient Eurasian mutation
that occurred thousands of years ago.
Also known as: WM.
It is the combination of a person's pair of gene alleles that influences traits.
The OR7D4 gene is located on chromosome 19 and encodes the protein named "Olfactory receptor 7D4", which influences the reported traits.
