Northern Congenital Abnormality Survey (NorCAS)


Around 2-3% of of newborn babies are born with a major congenital anomaly. Around 50% of births in England are covered by congenital anomaly registers, with NorCAS being the oldest. Data are collected for many uses, including to allow for auditing of antenatal screening techniques and to monitor for environmental causes of birth defects.

The Basics

Data collected from: 1985

Consent required from parent? No. NorCAS is part of the British Isles Network of Congenital Anomaly Registers (BINOCAR). BINOCAR applied for and was granted Section 60 Class Support under the Health and Social Care Act 2001 for the collection of personal information without consent on behalf of all the member registers.

Some examples of current work:

  • A study of brain malformations undertaken by Dr Anand Wagh, involving site visits to all neuroradiological units in the region and a cross-vaidation with HES data. Supervised by Martin Ward Platt.

  • Maternal obesity and congenital anomaly risk. Led by Dr Judith Rankin and funded by BDF Newlife.
