Genes affected
AQP1 (HGNC:633): (aquaporin 1 (Colton blood group)) This gene encodes a small integral membrane protein with six bilayer spanning domains that functions as a water channel protein. This protein permits passive transport of water along an osmotic gradient. This gene is a possible candidate for disorders involving imbalance in ocular fluid movement. [provided by RefSeq, Aug 2016]
AQP1 Gene-Disease associations (from GenCC):
  • pulmonary arterial hypertension
