Exome and genome sequencing in a heterogeneous population of patients with rare disease: Identifying predictors of a diagnosis
J Pucel et al, Genetics in Medicine, March 1, 2024

From the abstract: "In this case control study, we reviewed data from 400 diagnosed and 400 undiagnosed randomly selected participants in the Undiagnosed Diseases Network (UDN), all of whom had undergone ES and/or GS. We analyzed factors associated with receiving a diagnosis by ES and/or GS. Factors associated with a decreased odds of being diagnosed included adult symptom onset, singleton sequencing, and having undergone ES and/or GS prior to acceptance to the UDN (48%, 51%, and 32% lower odds, respectively). Factors that increased the odds of being diagnosed by ES and/or GS included having primarily neurological symptoms and having undergone prior chromosomal microarray testing. "
