Frequency

X-linked chondrodysplasia punctata 2 is a rare genetic condition with a frequency of approximately 1 in 100,000 newborns. This condition is typically associated with mutations in the gene called EMP2, which is located on the X chromosome.

The frequency of X-linked chondrodysplasia punctata 2 may vary in different populations and geographic regions. It is more common in certain ethnic groups, such as individuals of European or Hispanic descent.

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.

Chondrodysplasia punctata 2 was first described by Hermann et al. in 1986, and since then, additional cases have been reported in scientific articles and recognized by the medical community.

The frequency of this condition can be determined through genetic testing, which can identify mutations in the EMP2 gene. Genetic testing is typically done in specialized genetic testing centers, and it can provide important information about the inheritance pattern and causes of X-linked chondrodysplasia punctata 2.

To learn more about the frequency of X-linked chondrodysplasia punctata 2, you can refer to resources such as OMIM (Online Mendelian Inheritance in Man) and PubMed, which provide scientific articles and references related to this condition.

In addition, the Genetic Testing Registry, a resource provided by the National Center for Biotechnology Information (NCBI), can provide further information about genetic testing options and other resources available for X-linked chondrodysplasia punctata 2.

Overall, X-linked chondrodysplasia punctata 2 is a rare genetic condition with a frequency of approximately 1 in 100,000 newborns. Genetic testing and resources from organizations such as OMIM and PubMed can support the diagnosis and management of this condition.

Causes

X-linked chondrodysplasia punctata 2 (CDPX2) is caused by mutations in the arylsulfatase E (ARSE) gene, which is located on the X chromosome. The ARSE gene provides instructions for making an enzyme called arylsulfatase E, which is involved in the breakdown of a molecule called 3β-hydroxysteroid sulfate.

Most cases of CDPX2 occur sporadically, meaning they are not inherited from parents. However, some cases can be inherited in an X-linked recessive manner. This means that the condition mainly affects males and is passed on from a carrier mother. Carrier females have one mutated ARSE gene and one normal ARSE gene, so they usually do not have symptoms of CDPX2 but have a 50% chance of passing the mutated gene to their children.

CDPX2 is a rare condition, with an estimated frequency of 1 in 100,000 to 1 in 200,000 newborns. It is particularly common in individuals of European descent.

Genetic testing is available to confirm a diagnosis of CDPX2. This testing can identify mutations in the ARSE gene and help determine the specific genetic changes responsible for the condition. Additional genetic testing may also be necessary to rule out other similar conditions, such as Conradi-Hünermann-Happle syndrome.

Learn more about the gene associated with X-linked chondrodysplasia punctata 2

X-linked chondrodysplasia punctata 2 is a rare genetic condition caused by mutations in the arylsulfatase E (ARSE) gene. This gene is also known by other names, such as ASPS, CDPX2, and PEX. It is located on the X chromosome.

The ARSE gene provides instructions for making an enzyme called arylsulfatase E. This enzyme plays a crucial role in the breakdown of certain molecules in the body. Mutations in the ARSE gene can lead to a deficiency or absence of arylsulfatase E, which disrupts the normal breakdown process.

Patients with X-linked chondrodysplasia punctata 2 typically exhibit characteristic features such as short stature, skeletal abnormalities, and facial dysmorphisms. This rare condition is often diagnosed in newborns and can be detected through genetic testing.

Genetic testing for X-linked chondrodysplasia punctata 2 can involve targeted gene sequencing or a more comprehensive panel that includes testing for other genes associated with similar conditions. Identification of ARSE gene mutations confirms the diagnosis of X-linked chondrodysplasia punctata 2.

There have been over 20 mutations identified in the ARSE gene, but the frequency and distribution of mutations can vary among different populations. The ARSE gene is cataloged in various scientific resources, such as the Online Mendelian Inheritance in Man (OMIM) and the Human Gene Mutation Database (HGMD).

Additional resources and support for individuals with X-linked chondrodysplasia punctata 2 and their families can be found through advocacy organizations, such as the Conradi-Hunermann-Happle Syndrome Alliance and the Genetic and Rare Diseases Information Center.

Inheritance

X-linked chondrodysplasia punctata 2 (CDPX2) is a rare genetic condition that is inherited in an X-linked recessive manner. This means that the condition is caused by mutations in the gene located on the X-chromosome.

CDPX2 is also known as Conradi-Hünermann-Happle syndrome. It is characterized by the presence of chondrodysplasia punctata, which is a condition where tiny dots or flecks of calcium are present in the cartilage. These dots or flecks can be seen on X-rays and are typically found in the long bones or in the cartilage of the nose and ears.

This condition is more common in females than in males. This is because females have two X-chromosomes, while males have one X-chromosome and one Y-chromosome. If a female inherits a mutated gene on one X-chromosome, she may still have a normal copy of the gene on her other X-chromosome, which can help to support normal development. In males, however, if the X-chromosome carries a mutation, there is no second X-chromosome to provide additional support, resulting in a more severe form of the condition.

The genetic information about CDPX2 is available in scientific publications and databases. The gene associated with this condition is called the emopamil-binding protein (EBP) gene. Other names for this gene include CDPX2 and SCPx. Genetic testing can be done to confirm a diagnosis of CDPX2 in a patient.

There are several resources available for learning more about CDPX2 and its genetic inheritance. The National Center for Biotechnology Information (NCBI) has a catalog of articles and genetic information on their website. The Online Mendelian Inheritance in Man (OMIM) database also provides information on CDPX2 and other related genetic diseases. Additionally, there are advocacy and support groups for CDPX2, such as the Conradi-Hünermann-Happle Advocacy Group, that provide resources and support for individuals and families affected by this condition.

In conclusion, X-linked chondrodysplasia punctata 2 is a rare genetic condition that is inherited in an X-linked recessive manner. It is more common in females and is caused by mutations in the EBP gene. Genetic testing can confirm a diagnosis of CDPX2, and there are resources available for learning more about the condition and its genetic inheritance.
