Late infantile GM1 gangliosidosis is a rare lysosomal disorder characterized by mental deterioration and progressive spastic, cerebellar, and extrapyramidal signs, without facial dysmorphisms and organomegaly. Neuroimaging findings have been reported in only a few cases. Here we report on predominant globus pallidus MR signal-intensity abnormalities in 2 patients with the late infantile form of GM1 gangliosidosis.

Preclinical evaluation of the efficacy and safety of AAV8-TNAP-D10 in Alpl-/- and AlplPrx1/Prx1 mouse models for the treatment of early and late-onset hypophosphatasia.

We previously documented successful resolution of skeletal and dental disease in the infantile and late-onset murine models of hypophosphatasia (HPP), with a single injection of an adeno-associated serotype 8 vector encoding mineral-targeted TNAP (AAV8-TNAP-D10). Here, we conducted dosing studies in both HPP mouse models. A single escalating dose from 4x108 up to 4x1010 (vg/b) was intramuscularly injected into 4-day-old Alpl-/- mice (an infantile HPP model) and a single dose from 4x106 up to 4x109 (vg/b) was administered to 8-week-old AlplPrx1/Prx1 mice (a late-onset HPP model).

Ceroid lipofuscinosis type 2 (CLN2) is caused by biallelic pathogenic variants in the TPP1 gene, encoding lysosomal tripeptidyl peptidase 1 (TPP1). The classical late-infantile phenotype has an age of onset between 2 and 4 years and is characterized by psychomotor regression, myoclonus, ataxia, blindness, and shortened life expectancy. Vision loss occurs due to retinal degeneration, usually when severe neurological symptoms are already evident.

As the management of Pompe disease depends on whether an individual has infantile onset Pompe disease (IOPD) or late onset Pompe disease (LOPD), the question of whether the phenotype can be predicted from specific pathogenic variants is becoming increasingly important. We reviewed published cases of Pompe disease in which IOPD versus LOPD and pathogenic GAA variants were assigned for specific individuals. We then compared variant types and locations versus phenotypes.

CLN2 disease (late infantile neuronal ceroid lipofuscinosis) is an autosomal recessive, neurodegenerative lysosomal storage disease that results from loss of function mutations in the gene, which encodes tripeptidyl peptidase 1. It affects the central nervous system (CNS) with progressive neurodegeneration and early death, typically at ages from 8 to 12 years. Twenty years ago, our phase I clinical trial treated subjects with CLN2 disease by a catheter-based CNS administration of an adeno-associated virus vector serotype 2 (AAV2) expressing the gene.

Metachromatic leukodystrophy (MLD) is a progressive demyelinating disorder resulting from the toxic accumulation of sulfatides. The stereotyped neurodegeneration of MLD is well understood, and cases are categorized into subtypes by age at neurologic onset: late infantile (LI), juvenile (J), and adult. The systemic burden of disease, such as gallbladder involvement, however, is less well characterized.
