View full coroner's concerns
Following a testing request made for Freddie on 20 February 2017, a report was issued from the laboratory at Great Ormond Street Hospital on 7 June 2017. It was headlined:

No clearly pathogenic variant detected. Diagnosis not confirmed.

spoke to Freddie’s father the following day and told him that Freddie’s genetic test results were “absolutely normal”.

In fact, Freddie did have a pathogenic gene mutation in the SCN1A gene and died as a result of Dravet Syndrome.

By the time the report was issued, Freddie had already sadly died and so of course the misdiagnosis had no consequences for him, but such a situation could have significant consequences for another child.
