The c.2089T>C (p.C697R) alteration is located in exon 10 (coding exon 10) of the ADARB2 gene. This alteration results from a T to C substitution at nucleotide position 2089, causing the cysteine (C) at amino acid position 697 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
