The c.168G>C (p.W56C) alteration is located in exon 1 (coding exon 1) of the HSD17B2 gene. This alteration results from a G to C substitution at nucleotide position 168, causing the tryptophan (W) at amino acid position 56 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
