The c.1778A>G (p.N593S) alteration is located in exon 14 (coding exon 14) of the MTMR6 gene. This alteration results from a A to G substitution at nucleotide position 1778, causing the asparagine (N) at amino acid position 593 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
