The c.881T>C (p.I294T) alteration is located in exon 8 (coding exon 8) of the ADGB gene. This alteration results from a T to C substitution at nucleotide position 881, causing the isoleucine (I) at amino acid position 294 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
