Abstract
GM1 gangliosidosis is a rare lysosomal storage disorder associated with β-galactosidase enzyme deficiency. There are three types of GM1 gangliosidosis based on age of symptom onset, which correlate with disease severity. In 2019, we performed a retrospective multicentric study including all patients diagnosed with GM1 gangliosidosis in France since 1998. We had access to data for 61 of the 88 patients diagnosed between 1998 and 2019. There were 41 patients with type 1 (symptom onset ≤6 months), 11 with type 2a (symptom onset from 7 months to 2 years), 5 with type 2b (symptom onset from 2 to 3 years), and 4 with type 3 (symptom onset >3 years). The estimated incidence in France was 1/210000. In patients with type 1, the first symptoms were hypotonia (26/41, 63%), dyspnea (7/41, 17%), and nystagmus (6/41, 15%), whereas in patients with type 2a, these were psychomotor regression (9/11, 82%) and seizures (3/11, 27%). In types 2b and 3, the initial symptoms were mild, such as speech difficulties, school difficulties, and progressive psychomotor regression. Hypotonia was observed in all patients, except type 3. The mean overall survival was 23 months (95% confidence interval [CI]: 7, 39) for type 1 and 9.1 years (95% CI: 4.5, 13.5) for type 2a. To the best of our knowledge, this is one of the largest historical cohorts reported, which provides important information on the evolution of all types of GM1 gangliosidosis. These data could be used as a historical cohort in studies assessing potential therapies for this rare genetic disease.

Abstract
A male Japanese domestic cat with retarded growth in Hokkaido, Japan, showed progressive motor dysfunction, such as ataxia starting at 3 months of age and tremors, visual disorder and seizure after 4 months of age. Finally, the cat died of neurological deterioration at 9 months of age. Approximately half of the peripheral blood lymphocytes had multiple abnormal vacuoles. Magnetic resonance imaging showed bisymmetrical hyperintensity in the white matter of the parietal and occipital lobes in the forebrain on T2-weighted and fluid-attenuated inversion recovery images, and mild encephalatrophy of the olfactory bulbs and temporal lobes. The activity of lysosomal acid β-galactosidase in leukocytes was negligible, resulting in the biochemical diagnosis of GM1 gangliosidosis. Histologically, swollen neurons characterized by accumulation of pale, slightly granular cytoplasmic materials were observed throughout the central nervous system. Dysmyelination or demyelination and gemistocytic astrocytosis were observed in the white matter. Ultrastructually, membranous cytoplasmic bodies were detected in the lysosomes of neurons. However, genetic analysis did not identify the c.1448G>C mutation, which is the single known mutation of feline GM1 gangliosidosis, suggesting that the cat was affected with a new variant of the feline disease.

Abstract
OBJECTIVES The aim of this study is to find out mutations of Turkish GM1 gangliosidosis patients and to make genotype-phenotype correlations. DESIGN AND METHODS β-galactosidase activities were measured by using fluorometric substrate. Mutation screening of 16 exons of β-galactosidase gene and mutation detection were done by PCR-SSCP and DNA sequencing, respectively. RESULTS Four new mutations, c.188_189insT in exon 2, c.569_570insA in exon 6, p.K142Q in exon 4, p.G190D in exon 6, and one known mutation p.P549L in exon 15, were identified in the β-galactosidase gene in 5 Turkish patients. Mutations in exons 4 and 6 are in the active site and mutation in exon is in the galactose-binding domain of the β-galactosidase gene. CONCLUSION This is the first mutational analysis performed in Turkish GM1 gangliosidosis patients and shows the molecular heterogeneity of the disease in Turkish population. All identified mutations result in severe enzyme deficiency and infantile phenotype.

Abstract
GM1-gangliosidosis is a lysosomal storage disorder caused by a deficiency of beta-galactosidase. It is mainly characterized by progressive neurodegeneration and in its most severe infantile form it leads to death before the age of four. We have performed molecular analysis of five patients with the infantile form of GM1-gangliosidosis originating from the Middle East (two from Saudi Arabia and three from the United Arab Emirates). We have identified four novel mutations and one previously reported mutation in the GLB1 gene. The first novel mutation found in the homoallelic state in a patient from Saudi Arabia, is a c.171C>G transversion in exon 2 which creates a premature stop codon. Northern blot analysis in fibroblasts from the patient showed no mRNA and expression studies in COS-1 cells showed complete absence of the 85kDa precursor protein and no catalytic activity. The second novel mutation is a splicing error in intron 2, c.245+1G>A. This mutation was found in the heteroallelic state in a patient from Saudi Arabia, the second mutation being the previously described c.145C>T mutation. The third novel mutation is a missense mutation in exon 4, c.451G>T, found in the homoallelic state in a patient from the United Arab Emirates. Expression studies of this mutation in COS-1 cells showed complete absence of the 85kDa precursor protein and no catalytic activity. The fourth novel mutation is a splicing mutation in intron 8, c.914+4A>G, found in the homoallelic state in two siblings from the United Arab Emirates. This study has revealed genetic heterogeneity of the beta-galactosidase deficiency in the Arabic population [corrected]
