Overview

All of us have a 1 in 2 lifetime risk of cancer, but some common cancers – breast, melanoma, pancreatic, prostate and ovarian – are known to occur more frequently in families, passing from one generation to the next. This is because certain gene mutations can be inherited. Perhaps the most commonly talked about are the BRCA 1 and BRCA 2 genes, where mutations can indicate increased risk of developing breast, melanoma, pancreatic, prostate and ovarian cancers.

The 30-gene Pan Cancer Panel test from Everything Genetic, examines BRCA1 and BRCA2 and an additional 28 genes which can also indicate risk in the areas of uterine, colorectal (bowel) and stomach cancer.

Why have this test?

Knowing you have a genetic mutation enables you to make sure you have the appropriate regular screening and investigations. Many mutations are known to be hereditary; if you have a mutation, there is a 50% chance that your siblings and children will have it too.

What genes are tested?

Genes APC, ATM, BAP1, BARD1, BMPR1A, BRCA1, BRCA2, BRIP1, CDH1, CDK4*, CDKN2A(p14ARF), CDKN2A(p16INK4a), CHEK2, EPCAM*, GREM1*, MITF*, MLH1, MSH2, MSH6, MUTYH, NBN, PALB2, PMS2*, POLD1*, POLE*, PTEN, RAD51C, RAD51D, SMAD4, STK11, TP53

What does the test involve?

This test is a simple saliva test that you can do in the clinic on the day of your assessment, or in your own home of you prefer – we do not need a blood sample. If you choose to add this test after your health assessment, you will receive a kit in the post with clear instructions on taking your sample, together with all the paperwork you need to sign and post to Everything Genetic. The Cancer 30 Gene Panel can be added to all our assessments for £495.

How long does reporting take?

Once your sample is received at the US laboratory, it will be sequenced, and your genes analysed. A report is then generated, usually within 5 weeks of the laboratory receiving your sample.

How will I get my results?

Your Preventicum doctor will explain the process in your consultation, and you will also have a counselling session with a consultant (usually the day after your Preventicum assessment) so you understand this fully before consenting for the test. Once your genes have been analysed, you will be sent your results from Preventicum. If there are any positive findings you will also be contacted by a Consultant Geneticist to discuss these, the implications, and next steps. If the results are negative but you still wish to discuss these further, a consultation can be arranged at no extra charge.

Discussing your results with a consultant geneticist will help you to:

  • Understand your risks
  • Monitor your health
  • Consider your lifestyle or diet
  • Protect your family

What your results mean for you:

Positive

A positive result does NOT mean you have cancer, or that you will definitely develop it. It does means that a mutation, or genetic change, has been identified in a specific gene that increases the chance of your developing certain cancers in your lifetime – and your personal results will provide more detailed information specific to you. There may also be implications for other members of your family – and this will also be discussed with you.

Negative

A negative result means that no mutations or genetic changes associated with an increased risk of the most common hereditary cancers were identified in the genes that were analysed.

The result does not eliminate your risk of developing cancer completely as there are other factors, such as lifestyle, or perhaps mutations not detected by current technology or mutations in other genes. Again, all this will be discussed with you.

Variant of uncertain significance

This is where a gene mutation has been found, but at present we do not know if this affects your risk of certain cancers. Our scientists use state-of-the-art techniques to classify variants according to American College of Genetics and Genomics guidelines. All clinically actionable variants (i.e. factors like pathogenic and likely pathogenic – in other words able to, or likely to cause a disease/condition) are confirmed using an alternative technology. We understand that this can sound complex, so if your results show you have an actionable variant, this will be explained to you.
