The c.1106A>G (p.K369R) alteration is located in exon 1 (coding exon 1) of the SLC46A2 gene. This alteration results from a A to G substitution at nucleotide position 1106, causing the lysine (K) at amino acid position 369 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
