Dr Audero's experiment did not manipulate the receptor gene directly but, rather, manipulated its activity using the switch.
And the fact that no changes in the receptor gene itself were noticed by Dr Morley does not mean this gene is not involved.
Previous estimates said there were only 400 HoFH patients in the U.S. but included only those people confirmed to have two defective copies of the LDL receptor gene.

We will routinely turn off genes that promote disease and aging such as the fat insulin receptor gene that tells the fat cells to hold onto excess fat.

These orexin cells were discovered from the study of narcolepsy, a disease in which people cannot stay awake, in the late 1990s by Emmanuel Mignot, a Stanford researcher, who found that dogs with a defective orexin receptor gene developed the condition.

To make their mice hypersensitive to explosives, the researchers altered the gene responsible for the DNT receptor so that the transgenic mice have as many as one million neurons in which the odor receptor is tuned to the fragrance of a land mine.
The problem is that obese humans very rarely show a mutation in either the gene for leptin or that for its receptor.
Later, Kobilka isolated the specific gene that serves as a DNA blueprint for that adrenaline receptor.
WHITEHOUSE: Two American Scientists Win Nobel Prize in Chemistry
He added that gene therapy to knock out the mutation of the key CCR5 receptor was a possibility for future treatment.
