The NEU1 gene is a gene that encodes the enzyme neuraminidase, also known as sialidase. This enzyme is involved in the breakdown of sialic acid-containing molecules. Mutations in the NEU1 gene are related to a genetic condition known as sialidosis. Patients with sialidosis lack functional NEU1 enzyme, leading to the accumulation of sialic acid in lysosomes and subsequent cellular dysfunction.

Scientific research on the NEU1 gene and its associated conditions has provided valuable information for understanding the genetic basis of health and disease. The NEU1 gene is listed in the catalog of genetic tests and is included in the Genetic Testing Registry and OMIM database. Variants in this gene and their functional changes have been described in multiple articles referenced in the PubMed database.

In addition to sialidosis, mutations in the NEU1 gene can also be associated with other diseases and conditions in both humans and mice. Testing for NEU1 gene mutations can help in the diagnosis and management of these conditions. The NEU1 gene plays a critical role in cellular function and its study contributes to our understanding of various genetic disorders.

Genetic changes in the NEU1 gene can lead to various health conditions. One such condition is sialidosis, which is characterized by a deficiency of the enzyme neuraminidase. Neuraminidase is responsible for breaking down certain substances in the body called sialic acids.

Articles, catalog resources, and scientific tests related to sialidosis can be found in databases such as OMIM (Online Mendelian Inheritance in Man) and PubMed. These resources provide information on the genetic changes in the NEU1 gene and their implications for patients.

Testing for genetic changes in the NEU1 gene can provide additional information about the condition and help in diagnosing patients. Genetic testing can be done through various methods, including sequencing the NEU1 gene for variant changes.

For both workers and companies, employer-sponsored health insurance is costly. For 2018, employers paid an average of $10,000 per employee to cover 70% of the cost of health insurance, leaving workers with a price tag of about $4,200 for the remaining 30% of the expense, CNBC

Signs and symptoms of sialidosis include developmental delay, coarse facial features, skeletal abnormalities, and enlarged organs. Other diseases related to genetic changes in the NEU1 gene may have similar signs and symptoms. It is important for healthcare professionals to consider sialidosis when evaluating patients with these clinical features.

The International Registry for Sialidosis provides a database of patients with sialidosis and other related conditions. This registry can be a valuable resource for researchers and healthcare professionals seeking information on patient cases, genetic changes, and treatment outcomes.

Sialidosis Sialidosis PubMed
NEU1 Sialidosis OMIM

Sialidosis is a genetic condition caused by changes (variants) in the NEU1 gene. This gene provides instructions for making an enzyme called sialidase, which is involved in breaking down certain substances in lysosomes. When the NEU1 gene has variants, the enzyme’s activity is reduced or absent, leading to the build-up of these substances in the lysosomes.

Gene and Variant Databases

When studying genes and their variants, it is crucial to have access to diverse resources that provide comprehensive information related to genetic conditions and their associated genes. These resources, commonly known as gene and variant databases, serve as registries for genes and variants and provide valuable information for researchers, healthcare providers, and patients.

Gene and variant databases collate scientific articles, clinical reports, and genetic testing results to create comprehensive libraries of genetic information. These databases act as centralized repositories, allowing easy access to information about genes, their variants, and the associated diseases or conditions.

One of the most widely used gene and variant databases is PubMed, a free resource developed by the National Center for Biotechnology Information (NCBI). PubMed provides access to a vast collection of scientific articles related to genetics, allowing researchers to explore the latest findings and developments in the field.

In addition to PubMed, there are several other databases specifically dedicated to storing gene and variant information. These databases include OMIM (Online Mendelian Inheritance in Man), which catalogs information on genetic disorders and associated genes, and GeneTests, a resource that provides information about genetic testing laboratories and available tests for various conditions.

For genes and variants associated with specific diseases or conditions, specialized databases are available. For example, for the NEU1 gene, which is responsible for sialidosis, a genetic disorder affecting lysosomes, there is a dedicated database called Sialidosis Gene Mutation Database. This database provides information about specific genetic changes in the NEU1 gene and their associated signs, symptoms, and disease severity.

These gene and variant databases are constantly updated with new scientific research and findings. They serve as valuable resources for both researchers and healthcare providers, offering a comprehensive and reliable source of information on genes, variants, and associated conditions.

When conducting research or providing healthcare, referring to these databases can help ensure accurate and up-to-date information is used. They play a crucial role in advancing genetic research, improving diagnosis and treatment, and ultimately enhancing the health and well-being of individuals affected by genetic conditions.
