The c.2221A>C (p.I741L) alteration is located in exon 23 (coding exon 23) of the ATP2C2 gene. This alteration results from a A to C substitution at nucleotide position 2221, causing the isoleucine (I) at amino acid position 741 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
