Abstract

Objectives: In this study, we describe a 54-year-old Indian woman who presented with clinical features of Kufs syndrome A (KSA) and Kufs syndrome B (KSB), as well as neuropathologic and genetic findings consistent with neuronal ceroid lipofuscinosis type 13 (CLN13). Subsequently, we review the clinicopathologic features of 20 patients with CLN13 reported in the literature.

Methods: Data and imaging were obtained from the patient's medical records. The patient was examined neuropathologically, and next-generation sequencing was performed.

Results: Clinical radiologic scans revealed bilateral cortical atrophy, ventriculomegaly, a thin corpus callosum, and cerebellar vermian atrophy. Pathologic examination was remarkable for NCL. Postmortem genetic testing revealed a homozygous cathepsin F (CTSF) indel variant. A review of 20 reported CLN13 patients revealed novel clinical subtypes, including KSB type I (KSB-I), KSB type II (KSB-II), and Kufs syndrome C (KSC).

Discussion: CLN13 was clinically heterogeneous. Most patients with CLN13 (14/20) did not present with classic KSB (KSB-I). Instead, 6 patients presented with KSB-II, 4 patients presented with KSC (including the present patient), and 3 patients presented with dementia. Our results expand the CLN13 clinical spectrum and emphasize the importance of screening CTSF variants in clinical dementia and movement disorder cohorts.

期刊介绍： Neurology: Genetics is an online open access journal publishing peer-reviewed reports in the field of neurogenetics. Original articles in all areas of neurogenetics will be published including rare and common genetic variation, genotype-phenotype correlations, outlier phenotypes as a result of mutations in known disease-genes, and genetic variations with a putative link to diseases. This will include studies reporting on genetic disease risk and pharmacogenomics. In addition, Neurology: Genetics will publish results of gene-based clinical trials (viral, ASO, etc.). Genetically engineered model systems are not a primary focus of Neurology: Genetics, but studies using model systems for treatment trials are welcome, including well-powered studies reporting negative results.
