Sequence Variants in TAAR5 & Other Loci Affect Human Odor Perception & Naming https://www.cell.com/current-biology/fulltext/S0960-9822(20)31343-9 A variant in TAAR5 affects the perception of fish odor. Interesting to consider in relation to pseudogenization of the olfactory receptors
While about half of human odorant receptors are thought to be pseudogenes with loss-of-function, the Decode Genetics folks show that some sequence variants in odorant receptor genes are not
loss-of-function.
