The c.569A>G (p.N190S) alteration is located in exon 4 (coding exon 3) of the NYAP1 gene. This alteration results from a A to G substitution at nucleotide position 569, causing the asparagine (N) at amino acid position 190 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
