The NAC is the world's largest and only centre in the UK specialising in diagnosis, research and management of amyloidosis and hereditary systemic autoinflammatory diseases (SAIDs).
The Jack O’Neill Laboratory of Amyloidosis Research and Diagnosis at the NAC provides a comprehensive molecular diagnostic service for hereditary amyloidosis and SAIDs. Our SAIDs and hereditary amyloidosis next generation sequencing (NGS) gene panels consist of up to date clinically relevant genes, as determined by our highly specialised clinical consultants.

For carrier, predictive testing or screening of a single gene we recommend the Sanger sequencing method. For testing of a wider range of genes, in particular for patients with suspected SAIDs, we recommend our NGS gene panel. The NGS libraries are prepared using the TruSeq Custom Amplicon method and sequenced on the Illumina MiSeq platform. The sensitivity of our SAIDs panel is sufficient to detect somatic variants (<10% of the minor allele frequency). We have lately identified numerous patients with late onset SAIDs due to acquired mutations.
In order for our genetics team to process the sample, please register and complete the on-line questionnaire using the link provided below. Our web link contains all the information needed to complete the application form prior to genetic testing.
Charges are £150 for carrier and predictive testing of known mutations, and £400 for screening of a single gene using the Sanger sequencing method. NGS gene panels for hereditary amyloidosis or SAIDs are £700. You will be requested to provide the purchase order number.
Our laboratory takes part in the European Molecular Genetics Quality Network (EMQN) External Quality Assessment (EQA) scheme for Hereditary Recurrent Fevers (HRF).
For any technical questions regarding the DNA testing please contact Dr Dorota Rowczenio tel +44 (0)20 7433 2760.
Requesting a test
To request molecular genetic screening the physician should follow the steps below. Before requesting a genetic test please ensure either EDTA blood or DNA sample is clearly labelled with full name and date of birth.
Step 1: Select the following site where you will be asked to register or login:
Step 2: Enter the patient’s details and select and complete one of two questionnaires (hereditary fever syndromes or amyloidosis) indicating if a single gene testing or the gene panel analysis should be applied when processing the sample.
Step 3: Once the questionnaire is completed, you will see instructions for specimen collection and posting. Please print the Patient Request Form and post together with the bloods/DNA to Specimen Reception at the National Amyloidosis Centre. You will receive an email acknowledging receipt of the samples. A report will be posted to you when tests are completed and checked, generally in 4-6 weeks for Sanger sequencing, and up to 12 weeks for the next generation gene panel request.
If you encounter any problems accessing this site please contact the Genetics Secretary, Melanie Fuller, tel +44 (0)20 7433 2830; fax +44 (0)20 7433 2817.
Predictive genetic testing and clinical advice
Any clinical advice, also including predictive genetic testing in asymptomatic individuals (for example, family screening), must be discussed with one of our consultant staff.
Requests for test results
Current turnaround time is 6-8 weeks. In case of an urgent test please contact the head of the Genetic Lab (Dorota Rowczenio) or the Genetics Secretary (Melanie Fuller). Please check with your Pathology or Genetics Laboratory for copies of reports before contacting the National Amyloidosis Centre as all reports are copied to the appropriate laboratory, where details have been provided, at the time of issue. Please contact our Genetics Secretary if you have not received a report within 6-8 weeks of your request.
Please note, it is our policy not to issue verbal results or to email reports. Reports are sent by Royal Mail, and can additionally be faxed to a secure number by prior arrangement. Requests for copies of reports on the day that your patient is in clinic cannot normally be accommodated. We usually require at least 24 hours notice in which to fax a copy of a report.
As part of its commitment to quality, the National Amyloidosis laboratory participates annually in the external quality assurance scheme run by the European Molecular Genetics Quality Network (EMQN) for hereditary recurrent fever (HRF). Copies of the results of these external quality assessments are available on request. Currently there is no equivalent scheme for hereditary amyloidosis.
Please help us improve the service and direct compliments and complaints in writing to the Quality Manager, Hadija Trojer.
