The c.458G>T (p.G153V) alteration is located in exon 6 (coding exon 5) of the ZNF317 gene. This alteration results from a G to T substitution at nucleotide position 458, causing the glycine (G) at amino acid position 153 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
