Freezer failure cited in loss of McLean tissue samples

An independent analysis has faulted a freezer’s digital controls for the loss of 147 brain samples that defrosted earlier this year at the Harvard-affiliated Brain Tissue Resource Center at McLean Hospital.

Among those samples were the brains of 54 people who had autism – nearly a quarter of the autism brain samples available for research into a condition that now affects 1 in 88 American children. At the time researchers said the collection, which took 14 years to amass, could set autism research back perhaps as long as a decade.
