The c.1954G>A (p.E652K) alteration is located in exon 21 (coding exon 20) of the ANO4 gene. This alteration results from a G to A substitution at nucleotide position 1954, causing the glutamic acid (E) at amino acid position 652 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
