The c.470G>A (p.C157Y) alteration is located in exon 4 (coding exon 4) of the ZNF678 gene. This alteration results from a G to A substitution at nucleotide position 470, causing the cysteine (C) at amino acid position 157 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
