The c.1840G>C (p.V614L) alteration is located in exon 5 (coding exon 4) of the ZNF432 gene. This alteration results from a G to C substitution at nucleotide position 1840, causing the valine (V) at amino acid position 614 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
