In a paper published May 5 in PLOS Biology, researchers connect the dots between AQP4 and sleep in people. They showed that individuals with a set of eight single nucleotide polymorphisms (SNPs) in AQP4 have more slow wave energy as they sleep, which is characteristic of deep states of slumber, than those without the variants. And they have better cognitive function after being sleep deprived than people without those SNPs.

Might be key for my ME, according to some recent experiences I still have.

from the introduction

The gene encoding AQP4 is located on chromosome 18 (18q11.2–q12.1) [13] (Fig 1). Several thousand single nucleotide polymorphisms (SNPs) in the noncoding regions of AQP4 have so far been identified, and their function(s) in the normal and diseased human brain is an active area of research. Human AQP4 SNPs have been shown to impair cellular water permeability and water homeostasis in vitro [14]. Moreover, an array of studies have associated human AQP4 SNPs with neurological disorders including Alzheimer’s disease progression [15], vascular depression phenotype [16], leukariosis [17], outcome after traumatic head injury [18], edema formation [19,20], and the risk of stroke [21]. These findings suggest a link between AQP4 and the development of brain diseases associated with waste deposition and fluid movements. Recently, a single variant within AQP4 was associated with a 15% to 20% change in AQP4 expression [22].
