Collection Method: clinical testing

The c.385C>T (p.R129W) alteration is located in exon 2 (coding exon 2) of the ZNF783 gene. This alteration results from a C to T substitution at nucleotide position 385, causing the arginine (R) at amino acid position 129 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
