Genes affected

HSD17B12 (HGNC:18646): (hydroxysteroid 17-beta dehydrogenase 12) This gene encodes a very important 17beta-hydroxysteroid dehydrogenase (17beta-HSD) that converts estrone into estradiol in ovarian tissue. This enzyme is also involved in fatty acid elongation. [provided by RefSeq, Oct 2011]

The c.584C>G (p.P195R) alteration is located in exon 8 (coding exon 8) of the HSD17B12 gene. This alteration results from a C to G substitution at nucleotide position 584, causing the proline (P) at amino acid position 195 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
