Grange syndrome, also known as YY1AP1 gene related disorder, is a rare condition characterized by a complex of bone defects and associated abnormalities. It is an autosomal dominant genetic disorder, meaning it can be inherited from one affected parent. Grange syndrome affects multiple aspects of the body, including the bones and other associated defects of the toes. The frequency of this syndrome is unknown, but it is considered a rare genetic disease.

The Grange Syndrome is named after the Grange family, who were the first to describe the condition. It was first recorded in the scientific literature in 2018. Additional information about the syndrome can be found in scientific articles and genetic resources. The Online Mendelian Inheritance in Man (OMIM) catalog provides more information about the genetic inheritance and genes associated with this condition.

Genetic testing can be done to confirm the diagnosis of Grange syndrome and to learn more about the specific gene involved. The YY1AP1 gene is often tested for mutations associated with this condition. Genetic testing can also help identify other associated defects and provide important information for patient support and advocacy. Resources such as patient support groups and advocacy organizations can provide more information and support for individuals and families affected by Grange syndrome.

The Grange syndrome is a rare genetic condition. It has also been referred to by other names such as the yy1ap1 syndrome or the narrowing of bone with toes learning on complex gene defects syndrome. The frequency of this syndrome is not well defined, but it is considered to be a very rare condition.

There is limited information available about the Grange syndrome, and it is not cataloged in the OMIM (Online Mendelian Inheritance in Man) database. Scientific articles and references about this condition are scarce. However, as genetic testing becomes more accessible, there may be more resources and patient support available for individuals with the Grange syndrome.

Genetic testing can be done to determine if a person has the Grange syndrome. This testing involves analyzing specific genes and looking for associated defects. As of now, there is no known genetic cause for the Grange syndrome.

For more information and support on the Grange syndrome, you may consider reaching out to advocacy organizations or genetic testing centers. They may have further resources and information available to assist individuals and families affected by this rare condition.


The exact causes of Grange syndrome are not fully understood. However, it is believed to be a rare genetic condition with autosomal inheritance. This means that the condition is caused by changes in genes.

There have been several genes associated with Grange syndrome. One of the genes is YY1AP1, also known as Grange syndrome 1. Mutations in this gene have been found in individuals with Grange syndrome. Other genes may also be involved, but further research is needed to fully understand their role.

Grange syndrome is a complex condition with a wide range of symptoms. It is characterized by bone defects, such as abnormal bone growth and bone density, as well as toe narrowing. These abnormalities can affect multiple bones in the body.

The frequency of Grange syndrome is not clear, but it is considered to be a rare condition. It has been reported in only a few individuals and families worldwide.

Diagnosis of Grange syndrome usually involves genetic testing. This can help identify specific gene mutations that are associated with the condition. Genetic testing may also be used to rule out other genetic diseases that have similar symptoms.

There are several resources available for patients and families affected by Grange syndrome. These include advocacy organizations, patient support groups, and online forums where individuals can share information and experiences.

For more information about Grange syndrome and related genetic diseases, additional articles and scientific references can be found on websites such as OMIM and PubMed. These resources provide valuable information for both patients and healthcare professionals.

Learn more about the gene associated with Grange syndrome

Grange syndrome is a rare autosomal genetic disorder that causes bone defects and other related diseases. The syndrome is associated with mutations in the YY1AP1 gene, which is part of a complex genetic network.

Research studies have shown that the YY1AP1 gene plays a crucial role in the formation and development of bone. Mutations in this gene can lead to narrowing of the bones, especially in the toes, resulting in the unique characteristics of Grange syndrome.

To learn more about the genetic basis of Grange syndrome, there are several resources available:

  1. PubMed: A scientific research database that provides articles and references on various topics. You can search for specific papers related to Grange syndrome and the YY1AP1 gene.
  2. OMIM (Online Mendelian Inheritance in Man): A catalog of various genetic disorders, including Grange syndrome. It provides comprehensive information about the associated genes and inheritance patterns.
  3. GeneTests: An online resource that offers genetic testing information for rare diseases. It may have testing resources and patient advocacy groups related to Grange syndrome.

By exploring these sources, you can gain a deeper understanding of the genetic complexities and underlying causes of Grange syndrome. Additional research and clinical studies are essential for further unraveling the mysteries surrounding this condition.


The Grange syndrome is a rare genetic condition that is inherited in an autosomal recessive manner. This means that both parents must carry a copy of the mutated gene for their child to be affected by the syndrome.

The genetic cause of the Grange syndrome is associated with mutations in the YY1AP1 gene. These mutations result in defects in bone development, leading to the characteristic features of the syndrome, such as shortened limbs and narrowing of the toes.

It is important for individuals with a family history of the Grange syndrome to undergo genetic testing to determine if they are carriers of the mutated gene. Genetic testing can also be performed on individuals who exhibit symptoms of the syndrome but do not have a known family history.

In addition to YY1AP1 mutations, there may be other genetic and environmental factors that contribute to the development of the Grange syndrome. Further research is needed to understand the complex causes of this condition.

For more information about the inheritance and genetic aspects of the Grange syndrome, the following resources may be helpful:

  • OMIM – offers detailed information on genes associated with the Grange syndrome
  • PubMed – provides scientific articles and research on the syndrome
  • Advocacy and support groups – offer support and resources for patients and families affected by the Grange syndrome
  • The Grange Syndrome Catalog – a comprehensive catalog of information and resources on the syndrome

By learning more about the inheritance and genetic causes of the Grange syndrome, we can better understand this rare condition and provide appropriate support and testing for affected individuals.

Other Names for This Condition
