The c.3362T>C (p.I1121T) alteration is located in exon 26 (coding exon 25) of the SLC9C1 gene. This alteration results from a T to C substitution at nucleotide position 3362, causing the isoleucine (I) at amino acid position 1121 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
