The SHANK3 gene is a genetic disorder associated with autism spectrum disorder and other related conditions. It is located on chromosome 22q13.3, and deletions or changes in this gene have been found in individuals with autism and other neurodevelopmental disorders.

Research has shown that the SHANK3 gene plays a critical role in the development and function of nerve cells, particularly in the communication between neurons. Changes in the SHANK3 gene can result in structural and functional abnormalities in the nerve cells, affecting the formation of synapses and the regulation of synaptic proteins.

Studies have also suggested a link between changes in the SHANK3 gene and changes in spine morphology, which may contribute to the difficulties in communication and social interaction seen in individuals with autism spectrum disorder. This gene is listed in the scientific literature and databases such as PubMed and OMIM, and additional information can be found in related articles and references.

Testing for changes in the SHANK3 gene can be done through genetic testing, and it may help in diagnosing individuals with autism spectrum disorder or other related conditions. This gene is just one of many genes that have been identified as potential contributors to autism spectrum disorder.

Further research is needed to fully understand the role of the SHANK3 gene and other genes in the development of autism spectrum disorder and related conditions. The findings from these studies could provide valuable insights into the underlying causes of these disorders and potentially lead to improved diagnostic tests and treatment options.

Genetic changes in the SHANK3 gene have been associated with several health conditions and syndromes. The SHANK3 gene is essential for the development and function of the connections between nerve cells, known as synapses, in the brain. Changes in this gene can lead to a range of developmental and neurological disorders.

Given the high cost of medical care, it’s hardly a shock that patients are drowning in medical debt. Almost 20% of American households have delinquent medical bills that affect their credit report, according to NBC News. Having medical bills in collections makes it more difficult for patients to engage in other economic activities, such as purchasing a home or securing a loan to start a business.

One of the most well-known conditions associated with SHANK3 gene changes is Phelan-McDermid syndrome. This syndrome is characterized by developmental delay, intellectual disability, and a range of physical and behavioral features. Individuals with Phelan-McDermid syndrome often have difficulties with communication, social interaction, and may exhibit repetitive behaviors.

Another condition related to genetic changes in SHANK3 is Autism Spectrum Disorder (ASD). ASD is a complex neurodevelopmental disorder characterized by difficulties in social interaction, communication challenges, and restricted, repetitive patterns of behavior. Some individuals with ASD have been found to have a genetic variant on the SHANK3 gene.

Delorme syndrome, also known as PTLS or 22q13.3 deletion syndrome, is another condition associated with SHANK3 gene changes. Individuals with Delorme syndrome may have intellectual disability, delayed or absent speech, and distinctive physical features. This syndrome is caused by a deletion on chromosome 22q13.3 that includes the SHANK3 gene.

Genetic testing can be used to identify changes in the SHANK3 gene and provide a diagnosis for individuals with these health conditions. There are several resources available for genetic testing, including databases such as OMIM and PubMed. These databases contain scientific articles, references, and additional information on genetic changes in SHANK3 and related conditions.

It is important for individuals with genetic changes in the SHANK3 gene, as well as their families and healthcare providers, to have access to reliable information and resources. Genetic counseling can provide valuable support and guidance for individuals and families affected by these conditions.

Overall, genetic changes in the SHANK3 gene can lead to a range of health conditions and syndromes, including Phelan-McDermid syndrome, Autism Spectrum Disorder, and Delorme syndrome. Further research is ongoing to better understand the specific role of this gene and its associated proteins in the development and function of the brain.

22q133 deletion syndrome

The 22q133 deletion syndrome refers to a genetic disorder caused by the deletion of a specific region on the long arm of chromosome 22. This region includes several genes that play important roles in the development and functioning of various systems in the body.

This syndrome is known to encompass a wide spectrum of symptoms and conditions, ranging from mild to severe. It is associated with an increased risk of autism spectrum disorder, intellectual disability, and other developmental delays.

Scientific research, such as studies by Bockmann et al. and Betancur et al., have extensively researched the connection between autism and the 22q133 deletion syndrome. These studies reference other articles, databases (such as OMIM), and genetic testing to further understand the genetic changes and conditions related to this syndrome.

One of the notable findings in research on the 22q133 deletion syndrome is its association with changes in the SHANK3 gene. The SHANK3 gene codes for proteins that are crucial for the normal development and functioning of nerve cells, particularly in the formation and maintenance of synapses and dendritic spines.

For individuals with this syndrome, additional tests and genetic counseling may be recommended to evaluate the impact of the gene variant on their health and related conditions. The registry and resources for this syndrome, such as the Delorme catalog and the Rastam registry, provide valuable scientific information about the condition.

In conclusion, the 22q133 deletion syndrome is a complex genetic disorder associated with a wide range of symptoms and conditions. The deletion on chromosome 22 affects multiple genes, including the SHANK3 gene, leading to significant impacts on neurological development and functioning.

Autism spectrum disorder

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder that affects communication, social interaction, and behavior. It is characterized by a wide range of symptoms and levels of impairment. ASD is thought to have a strong genetic component, with many genes and genetic changes implicated in the disorder.

One gene that has been extensively studied in relation to ASD is the SHANK3 gene. SHANK3 codes for a family of proteins that are involved in the development and function of synapses, the junctions between nerve cells that allow for communication. Changes in the SHANK3 gene have been found in individuals with ASD and other related disorders, such as Phelan-McDermid syndrome.

Phelan-McDermid syndrome is caused by a deletion or other genetic changes in the SHANK3 gene. This rare genetic condition is characterized by developmental delay, intellectual disability, and autism spectrum disorder. Individuals with Phelan-McDermid syndrome often have difficulties with communication and social interaction, as well as other health conditions.

In addition to SHANK3, many other genes have been implicated in ASD. These genes are involved in various biological processes and pathways related to brain development, synaptic function, and communication between nerve cells. Some of these genes include NLGN, NRXN, CNTNAP, and MECP2.

The discovery and identification of these genes have been facilitated by scientific research and the use of resources such as the Online Mendelian Inheritance in Man (OMIM) database, PubMed, and other databases. These resources provide valuable information, references, and scientific articles on genes, genetic changes, and related conditions.

Genetic testing can be used to identify changes in specific genes associated with ASD. There are various tests available, including chromosomal microarray analysis, whole exome sequencing, and targeted gene panel testing. These tests can help confirm a diagnosis of ASD, provide additional information about genetic changes, and inform treatment strategies.

In summary, autism spectrum disorder is a complex condition that involves genetic changes in multiple genes. The SHANK3 gene, along with other genes, plays a role in the development and function of synapses, which are crucial for communication between nerve cells. Understanding the genetic basis of ASD is important for improving diagnosis, treatment, and support for individuals with the disorder.
