The c.428A>G (p.K143R) alteration is located in exon 4 (coding exon 4) of the ZNF709 gene. This alteration results from a A to G substitution at nucleotide position 428, causing the lysine (K) at amino acid position 143 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
