Collection Method: clinical testing

The c.834T>G (p.C278W) alteration is located in exon 7 (coding exon 5) of the ZNF546 gene. This alteration results from a T to G substitution at nucleotide position 834, causing the cysteine (C) at amino acid position 278 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
