The c.1420A>G (p.K474E) alteration is located in exon 3 (coding exon 2) of the PLEKHM3 gene. This alteration results from a A to G substitution at nucleotide position 1420, causing the lysine (K) at amino acid position 474 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
