Feb 23, 2023

The c.1336C>T (p.R446W) alteration is located in exon 15 (coding exon 14) of the ANO4 gene. This alteration results from a C to T substitution at nucleotide position 1336, causing the arginine (R) at amino acid position 446 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
