Sheldon-Hall Syndrome, also known as distal arthrogryposis type 2B, is a rare genetic condition that affects the muscles and joints, causing limited movement and contractures in the hands, feet, and other parts of the body. It is caused by mutations in the MYH3 gene, a gene that provides instructions for making a protein called myosin, which is involved in muscle contraction.
People with Sheldon-Hall Syndrome are typically born with joint contractures, tight skin, and distinctive facial features. The severity of the condition can vary, with some individuals experiencing mild symptoms while others have more severe limitations in movement. The exact frequency of the syndrome is unknown, but it is considered rare.
Research and scientific studies have provided valuable information about the causes, inheritance patterns, and clinical features of Sheldon-Hall Syndrome. The Online Mendelian Inheritance in Man (OMIM) and PubMed databases contain additional resources and articles on this condition, while the Genetic and Rare Diseases Information Center (GARD) provides support, advocacy, and resources for patients and their families.
Genetic counseling and testing can help identify the specific gene mutations associated with Sheldon-Hall Syndrome and provide individuals with important information about the prognosis, management, and care of the condition. ClinicalTrials.gov lists ongoing studies and trials related to this syndrome, offering opportunities for further research and advancements in treatment options.

Frequency
The Sheldon-Hall syndrome is a rare genetic disorder. Its frequency is not well documented.
A study published in the Journal of Medical Genetics in 2011 reported only a few dozen cases of Sheldon-Hall syndrome worldwide, indicating its rarity. The disease affects both males and females.
According to the Orphanet catalog, the prevalence of Sheldon-Hall syndrome is estimated to be around 1 in 200,000 people, making it a rare condition.
The exact causes of Sheldon-Hall syndrome are still not fully understood. However, several genetic mutations have been found to be associated with the condition. Mutations in genes such as TNNI2, MYH3, and TPM2 have been identified as potential causes.
The inheritance pattern of Sheldon-Hall syndrome is believed to be autosomal dominant, meaning that a person with a mutation in one copy of the gene can pass the disorder on to their children. However, some cases of the syndrome appear to be sporadic, occurring without any family history of the condition.
The Center for Rare Diseases and Vision Disorders at the Johns Hopkins University Carey School of Medicine and other advocacy groups offer resources and support for patients and families affected by Sheldon-Hall syndrome. They provide information about the syndrome, its genetic causes, and patient care.
Research on Sheldon-Hall syndrome is ongoing, with several clinical trials listed on ClinicalTrials.gov investigating possible treatments and therapies for the condition. These studies aim to improve the understanding and management of Sheldon-Hall syndrome.
Additional information about Sheldon-Hall syndrome, including its symptoms, diagnosis, and management, can be found on websites such as OMIM, PubMed, and other scientific resources.
In conclusion, Sheldon-Hall syndrome is a rare genetic disorder with a relatively low frequency. Further research and genetic studies are needed to fully understand the condition and develop effective treatments.
Causes
Sheldon-Hall syndrome is a rare genetic condition that is caused by mutations in the MYH3 or TNNI2 genes. These genes provide instructions for making proteins that are important for muscle contraction and development. Mutations in these genes can disrupt the normal function of muscle cells, leading to the signs and symptoms of Sheldon-Hall syndrome.
Sheldon-Hall syndrome can be inherited in an autosomal dominant or autosomal recessive manner. Autosomal dominant inheritance means that one copy of the mutated gene in each cell is sufficient to cause the disorder. Autosomal recessive inheritance requires two copies of the mutated gene in each cell. In some cases, the genetic cause of Sheldon-Hall syndrome is unknown.
According to scientific research and studies, mutations in the MYH3 gene have been found to be associated with distal arthrogryposis types 2A and 8, which are other rare disorders characterized by joint deformities. Mutations in the TNNI2 gene have been associated with distal arthrogryposis type 5, another condition characterized by joint deformities at birth.
More information about the genetic causes of Sheldon-Hall syndrome can be found on various resources such as OMIM, PubMed, and ClinicalTrials.gov. These resources provide scientific articles, studies, and clinical trials related to Sheldon-Hall syndrome and its genetic basis.
In addition to the genetic causes, environmental and other factors may also play a role in the development of Sheldon-Hall syndrome. Further research is needed to fully understand the causes and risk factors associated with this rare condition.
Learn more about the genes associated with Sheldon-Hall syndrome
Sheldon-Hall syndrome is a rare genetic disorder that is characterized by various skeletal abnormalities, such as contractures in the joints, short stature, and curved spine. It is caused by mutations in specific genes.
There are two genes that have been associated with Sheldon-Hall syndrome:
- MYH3: This gene provides instructions for making a protein that is involved in muscle development and function. Mutations in the MYH3 gene can disrupt the normal development of muscles, leading to the characteristic features of Sheldon-Hall syndrome.
- TNNI2: This gene encodes a protein that is essential for proper muscle contraction. Mutations in the TNNI2 gene can impair muscle function and contribute to the development of Sheldon-Hall syndrome.
Studies and research have shown that these genes are the main genetic causes of Sheldon-Hall syndrome. Additional genes may also be involved, but further studies are needed to fully understand their role.
If you want to learn more about the genes associated with Sheldon-Hall syndrome, here are some resources you can refer to:

Inheritance
Sheldon-Hall syndrome is a rare genetic condition that is inherited in an autosomal dominant manner. This means that individuals with one copy of the mutated gene have a 50% chance of passing the condition on to their children.
Several genes have been implicated in the development of Sheldon-Hall syndrome. Mutations in the TNNI2 and MYH3 genes have been identified in some individuals with this condition. These genes provide instructions for making proteins that are involved in muscle contraction.
It is important to note that not all individuals with Sheldon-Hall syndrome have identified mutations in these genes, suggesting that there may be additional genes involved in the development of this condition.
More research is needed to better understand the genetic causes of Sheldon-Hall syndrome. Ongoing scientific and clinical research, including studies on patient populations and genetic studies, may help to identify other genes associated with this condition.
For more information on the inheritance, genetic causes, and associated mutations of Sheldon-Hall syndrome, it is recommended to consult resources such as OMIM (Online Mendelian Inheritance in Man) and PubMed.
