The c.3476G>A (p.S1159N) alteration is located in exon 26 (coding exon 26) of the SBNO1 gene. This alteration results from a G to A substitution at nucleotide position 3476, causing the serine (S) at amino acid position 1159 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
