Ambry Genetics

Nov 18, 2023

The c.654C>G (p.S218R) alteration is located in exon 3 (coding exon 3) of the HSD17B2 gene. This alteration results from a C to G substitution at nucleotide position 654, causing the serine (S) at amino acid position 218 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
