A diagnostic confidence scheme for CLN3 disease.

ABSTRACT: Over the past 20 years, diagnostic testing for genetic diseases has evolved, leading to variable diagnostic certainty for individuals included in long-term natural history studies. Using genotype and phenotype data from an ongoing natural history study of CLN3 disease, we developed a hierarchical diagnostic confidence scheme with three major classes: Definite, Probable, or Possible CLN3 disease. An additional level, CLN3 Disease PLUS, includes individuals with CLN3 disease plus an additional disorder with a separate etiology that substantially affects the phenotype. Within the Definite and Probable CLN3 disease classes, we further divided individuals into subclasses based on phenotype. After assigning participants to classes, we performed a blinded reclassification to assess the reliabilit
