The c.1415T>C (p.I472T) alteration is located in exon 4 (coding exon 4) of the SLC46A2 gene. This alteration results from a T to C substitution at nucleotide position 1415, causing the isoleucine (I) at amino acid position 472 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
