The c.3223C>G (p.Q1075E) alteration is located in exon 25 (coding exon 24) of the SLC9C2 gene. This alteration results from a C to G substitution at nucleotide position 3223, causing the glutamine (Q) at amino acid position 1075 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
