The c.196G>T (p.G66W) alteration is located in exon 3 (coding exon 2) of the ZNF701 gene. This alteration results from a G to T substitution at nucleotide position 196, causing the glycine (G) at amino acid position 66 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
