The c.991A>G (p.T331A) alteration is located in exon 8 (coding exon 8) of the HNF4G gene. This alteration results from a A to G substitution at nucleotide position 991, causing the threonine (T) at amino acid position 331 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
