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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 30, 2023The c.307G>C (p.V103L) alteration is located in exon 1 (coding exon 1) of the AQP1 gene. This alteration results from a G to C substitution at nucleotide position 307, causing the valine (V) at amino acid position 103 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
