The frequencies of low-activity alleles of glucose-6-phosphate dehydrogenase in humans are highly correlated with the prevalence of malaria. These "deficiency" alleles are thought to provide reduced risk from infection by the Plasmodium parasite and are maintained at high frequency despite the hemopathologies that they cause. Haplotype analysis of "A-" and(More)
Two unrelated children and their siblings of Arab origin were diagnosed as having GM1 gangliosidosis on the basis of clinical features and markedly low levels of beta-galactosidase. The T2-weighted magnetic resonance images of the brain revealed certain characteristic features, including delayed myelination and abnormal appearance of the subcortical white(More)
We report a 3 1/2-year-old boy with congenital hypotonia, calf pseudohypertrophy, markedly delayed motor milestones and joint contractures. He was initially diagnosed to have congenital muscular dystrophy on the basis of the age of onset, a myopathic EMG, an elevated creatine kinase and a dystrophic muscle biopsy. Subsequently, dystrophin(More)
Starch binding domain-containing protein (Stbd)-1 is a carbohydrate-binding protein, which has been proposed as a selective autophagy receptor for glycogen. Here, we show that mouse Stbd1 is a transmembrane, endoplasmic reticulum (ER)-resident protein with the capacity to induce the formation of organized ER structures in HeLa cells. In addition to bulk ER,(More)
Fabry disease is an X-linked lysosomal storage disorder resulting from a deficiency of the hydrolytic enzyme α-galactosidase A (α-Gal-A). It is characterized by progressive lysosomal accumulation of globotriaosylceramide (Gb3) and multisystem pathology, affecting the skin, nervous and cerebrovascular systems, kidneys, and heart. Heterozygous females(More)
IMPORTANCE Duchenne muscular dystrophy (DMD) is a candidate for the recommended universal screening panel based on evidence that early corticosteroid treatment improves outcomes and on new genetic therapies that require early diagnosis for effectiveness. Elevated creatine kinase levels in the neonatal period are the initial screening marker in DMD newborn(More)
Tay-Sachs disease (TSD) is a recessively inherited neurodegenerative disorder caused by mutations in the HEXA gene resulting in β-hexosaminidase A (HEX A) deficiency and neuronal accumulation of GM2 ganglioside. We describe the first patient with Tay-Sachs disease in the Cypriot population, a juvenile case which presented with developmental regression at(More)
