The c.874G>A (p.D292N) alteration is located in exon 8 (coding exon 8) of the HNF4G gene. This alteration results from a G to A substitution at nucleotide position 874, causing the aspartic acid (D) at amino acid position 292 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
