Equity in action: The Diagnostic Working Group of The Undiagnosed Diseases Network International

From the abstract: "Rare diseases are recognized as a global public health priority. A timely and accurate diagnosis is a critical enabler for precise and personalized health care. However, barriers to rare disease diagnoses are especially steep for those from historically underserved communities, including low- and middle-income countries. The Undiagnosed Diseases Network International (UDNI) was launched in 2015 to help fill the knowledge gaps that impede diagnosis for rare diseases, and to foster the translation of research into medical practice, aided by active patient involvement.

Applications of genome sequencing as a single platform for clinical constitutional genetic testing
Y Yang et al, GIM Open, March 20, 2024

From the abstract: "The number of human disease genes has dramatically increased over the past decade, largely fueled by ongoing advances in sequencing technologies. In parallel, the number of available clinical genetic tests has also increased, including exome sequencing for undiagnosed diseases. Although most clinical sequencing tests have been centered on enrichment-based multigene panels and exome sequencing, the continued improvements in performance and throughput of genome sequencing suggest that this technology is emerging as a potential platform for routine clinical genetic testing.

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. "
