Finding Answers to Neurological Disorders with Clinical Exome Sequencing

blog image

At Ambry, “Finding Answers” is at the core of what we do.  We know patients and clinicians depend on us to find answers that help them better understand diseases, and improve outcomes.  

2017 has been a busy and productive year for Ambry.  In particular, using Ambry’s clinical exome test, ExomeNext, we have been successful in identifying many new disease-causing genetic mutations.    Working with leading scientists and clinicians, Ambry has been able to help identify the genetic causes of many mysterious disorders.   We are excited to share with you the novel gene-diseases associations we have discovered and their associated publications in the table below. 

We also want to give a special thank you to the patients, scientists and clinicians who have participated in these studies.  Ambry could not have made these new advances without their courage and commitment. 

As we look forward to 2018, we look forward to serving the patients and families that depend on us for answers.
