The c.3542C>T (p.P1181L) alteration is located in exon 18 (coding exon 18) of the ANO8 gene. This alteration results from a C to T substitution at nucleotide position 3542, causing the proline (P) at amino acid position 1181 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
