The c.426C>A (p.N142K) alteration is located in exon 4 (coding exon 4) of the HNF4G gene. This alteration results from a C to A substitution at nucleotide position 426, causing the asparagine (N) at amino acid position 142 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
