The c.3878C>A (p.T1293N) alteration is located in exon 32 (coding exon 31) of the SBNO2 gene. This alteration results from a C to A substitution at nucleotide position 3878, causing the threonine (T) at amino acid position 1293 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
