The c.3854G>T (p.G1285V) alteration is located in exon 32 (coding exon 31) of the SBNO2 gene. This alteration results from a G to T substitution at nucleotide position 3854, causing the glycine (G) at amino acid position 1285 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
