The c.806A>G (p.D269G) alteration is located in exon 3 (coding exon 3) of the TNFAIP8L3 gene. This alteration results from a A to G substitution at nucleotide position 806, causing the aspartic acid (D) at amino acid position 269 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
