Batten disease: biochemical and molecular characterization revealing novel PPT1 and TPP1 gene mutations in Indian patients.

ABSTRACT:

Background

Neuronal ceroid lipofuscinoses type I and type II (NCL1 and NCL2) also known as Batten disease are the commonly observed neurodegenerative lysosomal storage disorder caused by mutations in the PPT1 and TPP1 genes respectively. Till date, nearly 76 mutations in PPT1 and approximately 140 mutations, including large deletion/duplications, in TPP1 genes have been reported in the literature. The present study includes 34 unrelated Indian patients (12 females and 22 males) having epilepsy, visual impairment, cerebral atrophy, and cerebellar atrophy.

Methods

The biochemical investigation involved measuring the palmitoyl protein thioesterase 1 and tripeptidy peptidase l enzyme activity from the leukocytes. Based on the biochemical analysis all patients were screened for v
