Genes affected
ANO1 (HGNC:21625): (anoctamin 1) Enables calcium activated cation channel activity; intracellular calcium activated chloride channel activity; and iodide transmembrane transporter activity. Involved in cation transport; inorganic anion transport; and positive regulation of insulin secretion involved in cellular response to glucose stimulus. Located in apical plasma membrane and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.550A>G (p.I184V) alteration is located in exon 4 (coding exon 4) of the ANO1 gene. This alteration results from a A to G substitution at nucleotide position 550, causing the isoleucine (I) at amino acid position 184 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
