The c.453G>C (p.K151N) alteration is located in exon 2 (coding exon 2) of the HSD17B2 gene. This alteration results from a G to C substitution at nucleotide position 453, causing the lysine (K) at amino acid position 151 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
