About The Jnetics Clinic

The Jnetics Clinic operates virtually via video call. Individuals – book your appointment here. Couples, book your appointment here. Once you have booked your appointment and filled the registration form, we will then send a screening pack to you in the post (including a saliva sample kit).  The genetic counsellor will send you a ZOOM link in advance of the appointment. During the call she will give you instructions about providing your sample and posting it back to us/the lab.

Our test is due to be updated on September 1st to include a greater number of disorders, including those relevant to the Sephardi/Mizrahi community. If you book an appointment after this date, you will be offered the new test and not the current test of 9. The genetic counsellor will be able to provide you with more information on the new disorders during your appointment. If you have any questions at this stage about this please email screening@jnetics.org

What are Jewish genetic disorders?

Jewish people, as with all ethnic groups, are at greater risk of inheriting certain genetic conditions relative to the general population. Many people have heard of Tay-Sachs, but research has identified other serious genetic disorders that disproportionately affect people of Jewish origin. Like Tay-Sachs, these can also potentially be prevented through effective carrier screening.

What is carrier screening?

Carrier screening involves taking a saliva sample from an individual and testing it to identify if that person is a ‘carrier’ of a genetic condition.

Carriers of recessive conditions are NOT affected themselves but are at high risk of passing on a genetic disorder to their children if their partner is also a carrier of the SAME disorder.

Why have carrier screening for Jewish genetic disorders?

While Jewish genetic disorders vary in severity, those covered by Jnetics’ screening can all be very debilitating, almost all cause shortened lifespan and a few, like Tay-Sachs, are fatal in childhood.

1 in 5 people of Ashkenazi Jewish descent are a carrier of at least one of the main Jewish genetic disorders. Though rare, these conditions are devastating and most lack any effective treatment at this time – and typically occur even when there is no family history.

Carrier screening helps you to identify if you are at increased risk of passing on a severe genetic disorder and enables you to consider the different options available to reduce the chances of having an affected child.

Which disorders are covered?

The disorders covered in Jnetics’ screening are listed below – for more information about each, click on the disorder names.

Disorder Population at risk and Carrier Frequency
Tay Sachs Disease Ashkenazi Jewish: 1 in 25, Moroccan Jewish: 1 in 110, Iraqi Jewish: 1 in 140
Cystic Fibrosis Ashkenazi Jewish: 1 in 25-29, Sephardi Jewish: approx 1 in 30
Familial Dysautonomia Ashkenazi Jewish: 1 in 30
Canavan Disease Ashkenazi Jewish:1 in 40-57
Glycogen Storage Disorder (type 1a) Ashkenazi Jewish:1 in 71
Fanconi Anaemia (type C) Ashkenazi Jewish:1 in 89
Niemann-Pick Disease (type A) Ashkenazi Jewish:1 in 90
Bloom Syndrome Ashkenazi Jewish:1 in 100
Mucolipidosis IV Ashkenazi Jewish:1 in 100-125

Who is eligible for screening at the Jnetics Clinic?

Screening is available for anyone aged 16 and over and who is of Jewish descent; having at least one Ashkenazi Jewish grandparent. 

The test covers 9 recessively inherited disorders, all of which have increased prevalence in the Ashkenazi Jewish population, and 2 of which have increased prevalence in the Sephardi Jewish population. Therefore:

  • The test is more clinically useful for individuals of Ashkenazi origin (1 or more Ashkenazi grandparent) than those with Sephardi-only ancestry.
  • The test is relevant, but to a limited degree, to those of Sephardi-only origin.
  • If you and your partner have only Sephardi ancestry, please email screening@jnetics.org for advise about participation in our screening. (Please note: we hope to alter our test by August 2021 to include an increased number of Sephardi disorders).
  • For couples who are not pregnant, the partner who has full Ashkenazi ancestry may register for screening first.

The test is particularly important for people who are planning to start or expand their existing family, either now or in the future.

Any individual of Jewish ancestry with a known mutation or family history involving one of these 9 genes is welcome to register, providing details of the family history and/or test report.

It is also possible to get tested if you are already pregnant. However, if you will be over 11 weeks pregnant by time of your appointment, please contact us at screening@jnetics.org so that we can discuss with you the implications and options available for screening in later stage pregnancy.

If I am in a relationship, do both me and my partner need to get screened and what is the cost of screening?

Due to the nature of recessive inheritance, both partners of a couple need to be a carrier for the same disorder for the couple to be at risk of having an affected child.

Therefore if it would be acceptable for one partner to get screened first, and for the other partner to get screened afterwards, only if the first partner was identified as carrier.

Alternatively, for the sake of speed and cost efficiency, couples can choose to both get screened together from the outset. Couples choosing to do so can benefit from our reduced couples rate, as shown below.

The cost of screening for an individual is £250. Click HERE to book

Couples who wish to be screened together can do so at the reduced rate of £350. Click HERE to book. 

Please note, if a couple a currently pregnant or imminently wanting to conceive, we would recommend both partners getting screened at once.

Jnetics’ fundraises to subsidise the clinic costs. Payment directly covers the lab testing and clinical admin. Additional costs involved in delivering the service and providing counselling support are being subsidised by Jnetics in order to keep the real price of screening as low as possible.

Payment needs to be made online when completing the online registration form.

If you are interested in screening but are unable to afford the subsidised rate, please contact us at screening@jnetics.org as there may be an option to offer some limited financial assistance.

What does the screening process involve?

1) Online Registration- this includes picking an appointment time and paying the screening fee. Participant must register no later than one week prior to the selected appointment date.

2) Receiving the Screening Pack – participant receives a screening pack in the post with everything they need for the appointment. This includes forms and a saliva collection kit.

3) Video Appointment via Zoom with Genetic Counsellor– participant receives a zoom link ahead of the appointment. During the zoom appointment, the genetic counsellor (GC) answers any outstanding questions and guides the participant through the consent process. The participant then provides a saliva sample.

4) Posting the Completed Saliva Kit – the participant posts the completed saliva kit to Jnetics and Jnetics sends it on to the lab.

5) Receiving Results – results are received by email from the GC 8-11 weeks after the appointment, or 4-5 weeks if the participant (or their partner) is pregnant. If found to be a carrier of one of the conditions, it is possible for the participant to contact the GC for further information, advice and referrals, if relevant.
