Abstract
We report the case of a female child with INCL, who developed early and dramatic decreased rate of head growth with acquired microcephaly and marked cerebral atrophy, a relatively late appearance of severely progressive epilepsy (displaying a ‘‘vanishing’’ EEG pattern), GRODs in a skin biopsy, and hypertrophic cardiomyopathy. Defective enzymatic activity of CTSD was detected by a mass spectrometry (MS)-based assay in dried blood spots (DBSs). Sanger sequencing showed that the child harbored a novel homozygous c.205G>A, p.Glu69Lys located in exon 2 of CTSD.
