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 GeneticsNov 01, 2022The c.148G>A (p.V50M) alteration is located in exon 1 (coding exon 1) of the AQP1 gene. This alteration results from a G to A substitution at nucleotide position 148, causing the valine (V) at amino acid position 50 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
