Child TBI Genetics study

Contact: Dr Kelly Jones:

This study involved the collection of saliva samples from children who participated in a longitudinal, population-based study of traumatic brain injury (TBI) incidence and outcomes in the Hamilton and Waikato region. The HRC-funded Brain Injury Outcomes New Zealand in the Community (BIONIC) study identified all cases of TBI between 01/03/2010 to 28/02/2011.

The current study was completed in three consecutive stages:

1) Saliva samples were collected from children aged 3-7 years at the time of injury who had already participated in extensive BIONIC baseline and follow-up outcome assessments;

2) Saliva samples were then sent for DNA extraction and genetic analysis to the University of Auckland; and

3) child genetic data will be added to the existing BIONIC data set containing extensive information about each child’s injury and recovery.

By adding genetic information to the data set, researchers will have the ability to begin to examine genetic contributions to recovery from childhood TBI.
