Collection Method: clinical testing

The c.664T>C (p.C222R) alteration is located in exon 7 (coding exon 5) of the ZNF546 gene. This alteration results from a T to C substitution at nucleotide position 664, causing the cysteine (C) at amino acid position 222 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
