The c.1365A>C (p.K455N) alteration is located in exon 13 (coding exon 13) of the MARK1 gene. This alteration results from a A to C substitution at nucleotide position 1365, causing the lysine (K) at amino acid position 455 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
