Universal screening for Canavan's disease is not recommended. Testing should be available to individuals who meet the relevant clinical criteria.

 

Why is screening not recommended by UK NSC?

A whole population, carrier screening programme for Tay Sachs Disease, Canavan Disease and Familial Dysautonomia is not recommended.

While these conditions represent serious inherited health problems, they are very rare and the risk of inheritance is concentrated in the UK's Jewish population. As such, test coverage in this small, high risk population is not within the remit of the UK NSC.

There is evidence that carrier information is valued by stakeholders and that carrier testing has been successful in preventing the birth of affected babies when targeted within this population.

The UK NSC is supportive of work to ensure that an NHS testing service is available to those wishing to access it.
