Steroid Genetics

Genetic testing for disorders of adrenal and gonadal steroidogenesis

DNA analysis is available for the following disorders of steroidogenesis:

  • CYP17 17 alpha-hydroxylase deficiency
  • CYP11B1 11 beta-hydroxylase deficiency
  • CYP11B2 aldosterone synthase deficiency
  • HSD17B3 17 beta-hydroxysteroid dehydrogenase deficiency
  • SRD5A2 5 alpha-reductase deficiency.

Sample requirements
For all genetic tests either a DNA sample or 4 mL whole blood collected into EDTA is required (2 mL usually adequate for a child). Consent for the test should be sought and sent with the sample. Forms are available if required. Please provide clinical and biochemical information to support the suspected diagnosis.
