Ambry Genetics

Apr 22, 2022

The c.298A>C (p.K100Q) alteration is located in exon 2 (coding exon 2) of the HSD17B2 gene. This alteration results from a A to C substitution at nucleotide position 298, causing the lysine (K) at amino acid position 100 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
