Collection Method: clinical testing

The c.1299G>C (p.W433C) alteration is located in exon 5 (coding exon 4) of the ZNF790 gene. This alteration results from a G to C substitution at nucleotide position 1299, causing the tryptophan (W) at amino acid position 433 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
