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.410C>T (p.S137L) alteration is located in exon 5 (coding exon 5) of the HSD17B12 gene. This alteration results from a C to T substitution at nucleotide position 410, causing the serine (S) at amino acid position 137 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
