The c.397G>A (p.E133K) alteration is located in exon 4 (coding exon 4) of the SLC44A1 gene. This alteration results from a G to A substitution at nucleotide position 397, causing the glutamic acid (E) at amino acid position 133 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
