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]

Collection Method:clinical testing

The c.17C>T (p.P6L) alteration is located in exon 1 (coding exon 1) of the HSD17B12 gene. This alteration results from a C to T substitution at nucleotide position 17, causing the proline (P) at amino acid position 6 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
