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.
