turn it down

SLC26A4: This gene is associated with congenital deafness.

a bitter taste

TAS2R4/TAS2R38: These genes code for proteins involved in the perception of bitter compounds in the lungs.

colour blindness

OPN1SW: This gene is involved in recognising the colour blue. When it is defective, it is associated with ‘blue colour blindness’.

hungry? full…?

LEP: This gene is involved in regulating our appetite.

cystic fibrosis

CFTR: This gene is associated with cystic fibrosis.

pump up the volume

SLC26A5: This gene codes for the prestin protein which is involved in hearing. It is a fast-working protein, hence its name.

an Olympic medal?

EPO: This gene codes for EPO, a hormone that stimulates the production of red cells and can thus increase an athlete’s performance.

the beginnings of the placenta

ERVWE1: This gene is the remnants of a viral infection in our distant ancestors, and could have played a role in the emergence of the placenta in mammals.

on fertility

ZP3: This gene codes for a protein found on the egg’s surface, which is recognised by the sperm.

a passage for water

AQP1: This gene codes for a protein – aquaporin – that acts as a channel for ferrying water molecules throughout our body.

energy maker

CYC S: This gene encodes a cytochrome, a protein which is involved in producing energy in our cells.
