The c.223A>G (p.K75E) alteration is located in exon 3 (coding exon 3) of the SLC44A1 gene. This alteration results from a A to G substitution at nucleotide position 223, causing the lysine (K) at amino acid position 75 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
