The c.744C>G (p.I248M) alteration is located in exon 2 (coding exon 2) of the SLC10A4 gene. This alteration results from a C to G substitution at nucleotide position 744, causing the isoleucine (I) at amino acid position 248 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
