In 1960, Robert Terry and Saul Korey identified membranous bodies within the neurons of Tay-Sachs patients that were filled with gangliosides. The membranous bodies possessed qualities similar to lysosomes, the cellular structures responsible for degrading toxic …
WebTay-Sachs disease is the major model for lysosomal storage diseases. Similarly, the work done in the 1980s on hexosaminidase has been used as a model for understanding the cell biology of many other lysosomal proteins. Current research encompassing the fields of enzymology, cell biology, and molecul … WebTay-Sachs disease (TSD) is the resulting disease. Absence (or near absence) of enzyme activity is required to damage neurons; neurons that have approximately half-normal activity are unaffected. Thus, TSD is autosomal recessive, requiring HEXA disease variant(s) on both paternally and maternally inherited genes (homozygosity or compound …
WebWe analyzed the complete HEXA gene in 34 Spanish patients with Tay–Sachs disease and the HEXB gene in 14 Spanish patients with Sandhoff disease. We identified 27 different mutations, 14 of which were novel, in the HEXA gene and 14 different mutations, 8 of which unreported until now, in the HEXB gene, and we attempted to correlate these mutations … Web5.14 Non-Mendelian Inheritance.
