The c.992A>G (p.N331S) alteration is located in exon 10 (coding exon 10) of the MARK1 gene. This alteration results from a A to G substitution at nucleotide position 992, causing the asparagine (N) at amino acid position 331 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
