The c.1240C>G (p.R414G) alteration is located in exon 11 (coding exon 11) of the SLC5A4 gene. This alteration results from a C to G substitution at nucleotide position 1240, causing the arginine (R) at amino acid position 414 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
