The c.1397T>C (p.V466A) alteration is located in exon 13 (coding exon 13) of the MARK1 gene. This alteration results from a T to C substitution at nucleotide position 1397, causing the valine (V) at amino acid position 466 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
