The c.1026A>C (p.Q342H) alteration is located in exon 8 (coding exon 8) of the HNF4G gene. This alteration results from a A to C substitution at nucleotide position 1026, causing the glutamine (Q) at amino acid position 342 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
