The c.3713C>G (p.T1238S) alteration is located in exon 28 (coding exon 28) of the SBNO1 gene. This alteration results from a C to G substitution at nucleotide position 3713, causing the threonine (T) at amino acid position 1238 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
