The c.2897G>A (p.S966N) alteration is located in exon 16 (coding exon 15) of the MTMR4 gene. This alteration results from a G to A substitution at nucleotide position 2897, causing the serine (S) at amino acid position 966 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
