The c.397A>G (p.K133E) alteration is located in exon 3 (coding exon 3) of the SLC35F3 gene. This alteration results from a A to G substitution at nucleotide position 397, causing the lysine (K) at amino acid position 133 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
