The c.209A>G (p.Q70R) alteration is located in exon 2 (coding exon 2) of the ATG16L2 gene. This alteration results from a A to G substitution at nucleotide position 209, causing the glutamine (Q) at amino acid position 70 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
