The c.3422G>T (p.G1141V) alteration is located in exon 28 (coding exon 27) of the SLC9C1 gene. This alteration results from a G to T substitution at nucleotide position 3422, causing the glycine (G) at amino acid position 1141 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
