Ambry Genetics

Jan 23, 2023

The c.612G>C (p.L204F) alteration is located in exon 3 (coding exon 3) of the HSD17B2 gene. This alteration results from a G to C substitution at nucleotide position 612, causing the leucine (L) at amino acid position 204 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
