The c.1306A>G (p.K436E) alteration is located in exon 5 (coding exon 4) of the SLC45A3 gene. This alteration results from a A to G substitution at nucleotide position 1306, causing the lysine (K) at amino acid position 436 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
