Clinical Research Center Activities

Newborn Screening

The goal is to improve outcomes of children identified with, or at risk for, Krabbe Disease. To achieve this goal, HJKRI established in 2006 the NYS Krabbe Consortium, a multidisciplinary group of child neurologists, geneticists, newborn screeners, neuroradiologists, transplanters and developmental pediatricians. The consortium identifies babies with positive newborn screens, places them in risk groups based on multidisciplinary standardized criteria, maintains them in long-term follow up and when appropriate refers them for possible hematopoietic cell transplantation.

The consortium has established a clinical/database registry of children with positive newborns screens/confirmatory testing located at the Clinical Center of the HJKRI. Additional goals of the registry include determining which neurodiagnostic tests, mass spectrometry, mutation analysis and/or GALC activity predict outcomes and to modify mandated tests, where necessary, based on biannual review of testing results. As a result of the work of the Krabbe consortium, the NYS newborn screening program has been widely accepted as the model for screening children with Krabbe and other lysosomal disorders.

The World Wide Krabbe Registry

Another goal of the Clinical Center is to improve understanding of the natural history of Krabbe Disease including whether clinical, biochemical, genetic and/or neurodiagnostic parameters might predict phenotype. To accomplish this goal, an international registry of patients with Krabbe Disease was established in 2008. Parent questionnaires and medical records are accessed and reviewed with a focus on clinical signs and symptoms, disease course, family history and results of biochemical, genetic and neurodiagnostic studies. In order to increase the number of patients with a known genotype, mutation analysis is performed on saliva and newborn blood spots. Results are then compared with clinical course to provide genotype/phenotype correlations. In addition, MRI discs from > 70 patients are being reviewed in an effort to correlate neuroradiologic findings with phenotype and disease course.

Increase Awareness

The third goal of the Clinical Center is to increase awareness of Krabbe Disease through education in partnership with HUNTER's HOPE Foundation, through scientific and clinical dissemination and through addresses to state newborn screening advisory panels. The highly successful ANNUAL WORKSHOP ON KRABBE DISEASE has increased awareness of the condition as well as fostered collaborations among investigators.

Clinical Care

The fourth goal of the Clinical Center is to provide clinical care for children with Krabbe Disease as well as those with positive newborn screens for the disease. A clinic was established by the Clinical Director at the Women and Children’s Hospital of Buffalo. In the future, as new therapies come on line, we anticipate having an active translational research component as part of the Clinical Center.
