Part Descriptions
LP150045-5 Sequencing
Sequencing is a method used to determine the sequence of individual genes, larger genetic regions (i.e. clusters of genes or operons), full chromosomes or entire genomes. Historically, most sequencing has been performed using the chain termination method developed by Frederick Sanger in 1977. PMID: 271968 Sequencing technologies have improved dramatically, making them cheaper, faster, and more accurate. Next-generation sequencing (NGS), also known as high-throughput sequencing, deep sequencing, and second-generation sequencing, is a type of technology that uses parallel sequencing of multiple small fragments of DNA to determine sequence. This "high-throughput" technology has increased the speed and amount of DNA sequenced at a significantly reduced cost. PMID: 18576944 Several NGS platforms (ie, sequencing instruments and associated reagents) have been developed. Third-generation sequencing is another methodology currently under development that uses parallel sequencing similar to NGS. In contrast to NGS, third-generation sequencing uses single DNA molecules rather than amplified DNA as a template. PMID: 20858600

LP186141-0 HEXB gene
The HEXB gene is located on chromosome 5q13.3 and encodes the beta subunit of beta-hexosaminidase, which is responsible for the degradation of GM2 gangliosides and other molecules containing terminal N-acetyl hexosamines. Beta-hexosaminidase is composed of two subunits, alpha and beta, which are encoded by the genes HEXA and HEXB, respectively. Mutations in both HEXA and HEXB lead to an accumulation of GM2 gangliosides in neurons result in neurodegenerative disorders termed the GM2 gangliosidoses. HEXA mutations are associated with Tay-Sachs disease (GM2-gangliosidosis type I), and HEXB mutations are associated with Sandhoff disease (GM2-gangliosidosis type II). In their classic forms, Tay-Sachs and Sandhoff diseases are clinically indistinguishable and are characterized by the onset of progressive neurodegeneration in infancy, followed by paralysis, dementia, and death by age 3.

LP186141-0 HEXB gene
The HEXB gene (hexosaminidase B (beta polypeptide)) [HGNC Gene ID:4879] is located on chromosome 5q13. Hexosaminidase B is the beta subunit of the lysosomal enzyme beta-hexosaminidase that, together with the cofactor GM2 activator protein, catalyzes the degradation of the ganglioside GM2, and other molecules containing terminal N-acetyl hexosamines. Beta-hexosaminidase is composed of two subunits, alpha and beta, which are encoded by separate genes. Both beta-hexosaminidase alpha and beta subunits are members of family 20 of glycosyl hydrolases. Mutations in the alpha or beta subunit genes lead to an accumulation of GM2 ganglioside in neurons and neurodegenerative disorders termed the GM2 gangliosidoses. Beta subunit gene mutations lead to Sandhoff disease (GM2-gangliosidosis type II). Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
