In May 2016, Davis contracted Respiratory Syncytial Virus (RSV) which rapidly progressed to Acute Respiratory Distress Syndrome (ARDS). Davis spent 3 weeks on a ventilator and a month in the Pediatric Intensive Care Unit (PICU).

Koolen-De Vries syndrome is a rare genetic condition caused by partial loss of part of chromosome 17 [17q21.31 microdeletion], including the KANSL1 gene. It can also be caused by a change in the KANSL1 gene. These genetic changes can cause developmental delays, learning difficulties, and create possible health concerns. However, individuals vary, both in the degree to which they are affected and in other effects.
