Collection Method: clinical testing

The c.622C>G (p.L208V) alteration is located in exon 5 (coding exon 5) of the ATG16L2 gene. This alteration results from a C to G substitution at nucleotide position 622, causing the leucine (L) at amino acid position 208 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
