They discovered a single-letter mutation in the ADRB1 gene and then tested their findings with mice to confirm that the mutant form of ADRBI promotes natural short sleep. Interestingly enough ...

Another is ADRB130652-X), which was identified by sequencing and analyzing the DNA of a family with three successive generations of natural short sleepers, who all had a single mutation in this gene.

But putting aside the fact that these individuals may have the short sleeper gene mutation which allows for this, the average person still needs the proper amount of sleep to function normally.

These people are called "short-sleepers," and scientists are only ... believe the capabilities are connected to specific genetic mutations, and have publicly identified one on the hDEC2 gene.

Well, not so fast. Short sleeper syndrome (SSS) affects people who naturally sleep for between four and six hours but still ...
