Search Links: General Info : Protocols : Patient Info

DescriptionNeuronal Ceroid Lipofuscinoses (commonly still referred to as Battens disease) are among the most common neurometabolic disorders. These are investigated by the measurement of the enzymes palmitoyl protein thioesterase (PPT) and tripeptidyl peptidase 1 (TPP). PPT is measured for the infantile forms INCL, NCL1 & CLN1. TPP is measured for the classic late infatile forms LINCL, NCL2 & CLN2.
IndicationFor investigating suspected cases of neuronal ceroid lipofuscinoses.
Additional InfoAn additional test for vacuolated lymphocytes (sometimes referred to as Battens histology) may be requested/required if initial enzyme tests are normal and there is still a strong clinical suspicion.
