The Comfort of a Diagnosis and Knowing You Are Not Alone

Emmy Anderson and her daughter Wren sharing a happy moment

When your child is sick with a rare condition that can’t be named, the search for an answer can seem frustrating and hopeless. For Kirk and Emmy Anderson, navigating the lengthy diagnostic process for their daughter, Wren, was something they endured with the hope that an answer would eventually come.

By about 6 months of age, Kirk and Emmy noticed that Wren was not meeting her developmental milestones. After a febrile seizure led to a stay in in Seattle Children’s Neonatal Intensive Care Unit (NICU), they received the news that a brain MRI showed Wren had a decrease in the amount of white matter in the brain, as well as a fluid filled sack growing between her brain and spinal cord. Despite the findings, doctors didn’t yet know what was causing these issues to arise.

New Gene Sequencing Technology Opens Door to Faster Diagnoses

Kaylyn Milligan and her son, Owen. Milligan lost two babies due to a genetic mutation she didn’t know she had. After a careful review of her genome, Dr. James Bennett was able to identify the mutation and Milligan was able to make educated family planning decisions.

There are times when a child comes to the hospital with symptoms and even after a thorough exam and many tests, doctors can have a difficult time making a diagnosis. Now, doctors and researchers at Seattle Children’s have a new tool that will be key in finding answers for patients and their families: A next generation gene sequencer that can be used to sequence DNA quickly and make diagnoses in complex cases.

The machine, an Illumina NextSeq, can sequence all of the genes in the human genome in just 24 hours. The enormous amount of data generated by this machine will be processed using the PierianDx analytical pipeline.

“This new technology will dramatically decrease the cost of gene sequencing for our patients and will help us make quicker diagnoses, especially in complicated cases,” said Dr. James Bennett, a geneticist and researcher at Seattle Children’s Hospital and Seattle Children’s Research Institute. “Families can sometimes go years without a diagnosis. Now, we’ll be able to provide more answers and identify potential therapies based on what we find in the genome.” Read full post »
