The c.568G>T (p.D190Y) alteration is located in exon 5 (coding exon 5) of the ATG16L2 gene. This alteration results from a G to T substitution at nucleotide position 568, causing the aspartic acid (D) at amino acid position 190 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
