Genes affected
ANO9 (HGNC:20679): (anoctamin 9) The protein encoded by this gene is a member of the TMEM16 (anoctamin) family of proteins, some of which form integral membrane calcium-activated chloride channels. The function of the encoded protein has yet to be elucidated, although it may have channel-forming abilities and also may have phospholipid scramblase activity. This gene has been observed to be upregulated in stage II and III colorectal cancers. [provided by RefSeq, Dec 2016]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.2299G>A (p.A767T) alteration is located in exon 23 (coding exon 23) of the ANO9 gene. This alteration results from a G to A substitution at nucleotide position 2299, causing the alanine (A) at amino acid position 767 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
