A polymerase chain reaction-based genotyping assay for detecting a novel Sandhoff disease-causing mutation.

Abstract excerpt

Sandhoff disease is a rare genetic disorder, however, some northern Saskatchewan communities have a high incidence of the disease (for which the causative mutation has not been described). We discovered a novel mutation causing Sandhoff disease in this community and validated a molecular assay to detect the mutant allele. DNA sequencing was used to search for mutations in the HEXB gene from the most recently...
