The c.3976A>G (p.S1326G) alteration is located in exon 30 (coding exon 30) of the SBNO1 gene. This alteration results from a A to G substitution at nucleotide position 3976, causing the serine (S) at amino acid position 1326 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
