The c.3703G>A (p.A1235T) alteration is located in exon 32 (coding exon 31) of the SBNO2 gene. This alteration results from a G to A substitution at nucleotide position 3703, causing the alanine (A) at amino acid position 1235 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
