PPP2R5D-related intellectual disability is a rare genetic disorder characterized by intellectual disability, developmental delays, and other associated clinical features. It is caused by mutations in the PPP2R5D gene, which is involved in regulating the activity of certain proteins in the brain. This disorder is inherited in an autosomal dominant manner, which means that a mutation in only one copy of the gene is enough to cause the condition.

Individuals with PPP2R5D-related intellectual disability typically have moderate to severe intellectual disability, delayed speech and language development, hypotonia (low muscle tone), and other physical features. They may also have behavioral problems, such as attention deficit hyperactivity disorder (ADHD) or autism spectrum disorder (ASD).

Research studies and clinical trials are ongoing to learn more about this condition and find better ways to diagnose and treat affected individuals. Information on the current studies can be found on clinicaltrialsgov. Additional scientific resources, articles, and references about PPP2R5D-related intellectual disability can be found on OMIM, PubMed, and other genetic databases.

Testing for mutations in the PPP2R5D gene can confirm a diagnosis of PPP2R5D-related intellectual disability. Genetic counseling and support groups can provide information and support for individuals and families affected by this disorder. Advocacy organizations also play a role in raising awareness and supporting research for PPP2R5D-related intellectual disability.

Frequency

The frequency of PPP2R5D-related intellectual disability is not well understood due to its rarity. However, current research and available resources provide some information on its occurrence.

Once you do get to see the doctor, don’t be surprised if you’re rushed out of the exam room before you get all of your questions answered, according to healthcare staffing agency Staff Care. Studies show that 41% of ophthalmologists spend just 9 to 12 minutes with a patient, and 13- to 16-minute appointments are the norm for 40% of cardiologists, 37% of pediatricians, 35% of urologists, 35% of family physicians, 34% of obstetricians and gynecologists and 30% of otolaryngologists.

1. Publications from scientific studies: PPP2R5D-related intellectual disability is considered a rare condition, with only a limited number of documented cases in medical literature. Several case reports and studies have described patients with this disorder, shedding light on its clinical presentation and associated symptoms.
2. OMIM: OMIM (Online Mendelian Inheritance in Man) is a comprehensive resource that catalogues information about genetic diseases. PPP2R5D-related intellectual disability is listed in OMIM, providing further documentation of the condition and its genetic basis.
3. ClinicalTrials.gov: ClinicalTrials.gov is a registry of clinical trials exploring various medical conditions. While there are currently no clinical trials specifically focused on PPP2R5D-related intellectual disability, the absence of such trials suggests that the condition is extremely rare.
4. Other genetic databases: Additional genetic databases may provide further information on the frequency of PPP2R5D-related intellectual disability. These resources can be explored to gather more data on the occurrence of this condition.

Overall, due to the limited number of reported cases and the rarity of PPP2R5D-related intellectual disability, it is considered a rare disorder. Further research and genetic testing may help in gaining a better understanding of the condition’s frequency and associated characteristics.

Causes

The main cause of PPP2R5D-related intellectual disability is a mutation in the PPP2R5D gene. This gene is located on the long arm of chromosome 1 (1q41) and provides instructions for making a protein that is part of an enzyme called protein phosphatase 2A. This enzyme is involved in the regulation of many cellular processes, including the growth and division of cells.

Scientists have found that mutations in the PPP2R5D gene lead to a decrease in the activity of protein phosphatase 2A. This reduced activity disrupts the normal functioning of cells, including those in the brain, leading to intellectual disability.

PPP2R5D-related intellectual disability is inherited in an autosomal dominant pattern, which means that a mutation in one copy of the PPP2R5D gene in each cell is sufficient to cause the disorder. Most cases of this condition are not inherited from parents; instead, they occur sporadically as a result of a new mutation in the gene that occurs during the formation of egg or sperm cells or early in embryonic development.

Additional scientific studies have identified other genes that may be associated with intellectual disability, but the PPP2R5D gene is currently the most well-characterized gene linked to this specific condition.

Testing for mutations in the PPP2R5D gene can confirm a diagnosis of PPP2R5D-related intellectual disability. Genetic testing may be recommended for individuals who have intellectual disability, developmental delay, hypotonia (weak muscle tone), or other features associated with this condition. A genetic counselor or other healthcare professional can provide more information about the benefits, limitations, and implications of genetic testing.

For more information about genes associated with intellectual disability, you can visit resources such as OMIM (Online Mendelian Inheritance in Man) and PubMed. These databases provide valuable information about the genetic basis of various diseases and can help individuals and families learn more about the condition and find additional support and advocacy resources.

Inheritance

PPP2R5D-related intellectual disability is a genetic disorder caused by mutations in the PPP2R5D gene. This gene provides instructions for making a protein that is involved in the regulation of cellular activities, including the activity of other genes.

The inheritance pattern of this condition is autosomal dominant, which means that a mutation in one copy of the PPP2R5D gene in each cell is sufficient to cause the disorder. In most cases, the mutation is inherited from a parent who also has the disorder. However, some cases may occur due to new mutations in the gene.

Intellectual disability associated with PPP2R5D mutations is characterized by developmental delays, cognitive impairment, and language difficulties. Other features may include hypotonia (decreased muscle tone), motor delay, and behavioral problems.

There are additional rare genetic diseases associated with intellectual disability that may have overlapping symptoms with PPP2R5D-related intellectual disability. Genetic testing can help determine the specific cause of the condition, and genetic counselors can provide more information about inheritance and recurrence risks.

Scientific research and studies are ongoing to learn more about the causes, frequency, and inheritance of PPP2R5D-related intellectual disability. The PPP2R5D gene and associated genes are being investigated to better understand their role in the development and function of the brain.

Advocacy groups and resources such as the PPP2R5D Foundation provide support and information for patients and families affected by this condition. They also promote research and raise awareness to improve the diagnosis and management of PPP2R5D-related intellectual disability.
