Genes affected
HSD17B3 (HGNC:5212): (hydroxysteroid 17-beta dehydrogenase 3) This isoform of 17 beta-hydroxysteroid dehydrogenase is expressed predominantly in the testis and catalyzes the conversion of androstenedione to testosterone. It preferentially uses NADP as cofactor. Deficiency can result in male pseudohermaphroditism with gynecomastia. [provided by RefSeq, Jul 2008]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 26, 2021This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 200 of the HSD17B3 protein (p.Ala200Val). This variant is present in population databases (rs142236065, gnomAD 0.007%). This missense change has been observed in individual(s) with clinical features of 17-beta hydroxysteroid dehydrogenase 3 deficiency (PMID: 25740850; Invitae). ClinVar contains an entry for this variant (Variation ID: 435472). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt HSD17B3 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
