The c.373A>G (p.R125G) alteration is located in exon 4 (coding exon 4) of the HNF4G gene. This alteration results from a A to G substitution at nucleotide position 373, causing the arginine (R) at amino acid position 125 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
