Nov 27, 2023

The c.667A>G (p.T223A) alteration is located in exon 4 (coding exon 4) of the ODF3L2 gene. This alteration results from a A to G substitution at nucleotide position 667, causing the threonine (T) at amino acid position 223 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
