They've recently discovered the CYP3A5 enzyme, which is part of the P450 enzyme family involved in drug metabolism.
Its structure varies genetically, causing differences in how people process medication.
This enzyme's discovery has significant medical implications, especially in personalised medicine.
It's led to an understanding that one drug doesn't fit all, and that individual's genetic makeup should be considered when prescribing medication.
It's a fascinating step forward in medical science.
