Mar 30, 2024

The c.238A>G (p.R80G) alteration is located in exon 5 (coding exon 5) of the ZNF326 gene. This alteration results from a A to G substitution at nucleotide position 238, causing the arginine (R) at amino acid position 80 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
