Genes affected

AQP11 (HGNC:19940): (aquaporin 11) Enables glycerol channel activity and water channel activity. Involved in several processes, including glycerol transport; hydrogen peroxide transmembrane transport; and protein homooligomerization. Located in cell surface; endoplasmic reticulum; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

AQP11 links:

CLNS1A (HGNC:2080): (chloride nucleotide-sensitive channel 1A) This gene encodes a protein that functions in multiple regulatory pathways. The encoded protein complexes with numerous cytosolic proteins and performs diverse functions including regulation of small nuclear ribonucleoprotein biosynthesis, platelet activation and cytoskeletal organization. The protein is also found associated with the plasma membrane where it functions as a chloride current regulator. Pseudogenes of this gene are found on chromosomes 1, 4 and 6. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2015]

The c.299C>T (p.P100L) alteration is located in exon 1 (coding exon 1) of the AQP11 gene. This alteration results from a C to T substitution at nucleotide position 299, causing the proline (P) at amino acid position 100 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
