Nonsyndromic aplasia cutis congenita is a rare congenital condition characterized by the absence of skin, most commonly on the scalp, but can occur on other areas of the body as well. This condition can be caused by various factors, including genetic mutations or other unknown causes. The frequency of this condition is not well-established, but it is considered to be a rare condition.

There have been a few scientific articles published on nonsyndromic aplasia cutis congenita, providing information about the condition and potential genetic causes. One such article from PubMed suggests that this condition may be caused by mutations in certain genes. However, further research and genetic testing is needed to support these findings and identify the specific genes involved.

While nonsyndromic aplasia cutis congenita is a rare condition, it can have significant impacts on patient growth and development. Additionally, it can cause emotional and psychological stress for both the affected individual and their family. Therefore, resources for support, advocacy, and information are crucial for those affected by this condition.

The Online Mendelian Inheritance in Man (OMIM) database is a useful resource for finding more information about nonsyndromic aplasia cutis congenita, including scientific references, genetic testing information, and other related articles. Additionally, there are advocacy groups and centers that specialize in this condition, which can provide support and additional resources for affected individuals and their families.

Frequency

This condition is rare, with a reported frequency of approximately 1 in 10,000 live births. It is not commonly inherited, and the exact inheritance pattern is still not well understood. However, there have been cases of familial inheritance reported in the medical literature.

Due to the rarity of this condition, there is limited information and advocacy surrounding it. There may be additional defects or diseases associated with aplasia cutis congenita, and further testing may be required to determine if there is an underlying genetic cause or if it is caused by other factors.

The per capita price of healthcare per year is higher in the United States than in any other nation in the world, according to National Public Radio (NPR). America spends nearly 2.5 times as much per person as the United Kingdom does, despite having comparable wealth and a lower life expectancy.

OMIM, a scientific database, includes information on aplasia cutis congenita and provides references to scientific articles and publications on the topic. Furthermore, PubMed, a resource for scientific literature, also contains rare case reports and scientific studies on this condition.

In terms of affected areas, aplasia cutis congenita can occur on the scalp, limbs, and trunk, among other places. The condition can vary in severity, with some cases involving only a small patch of missing skin, while others may have more extensive defects.

There are no specific genes currently associated with nonsyndromic aplasia cutis congenita, but ongoing research may help identify any potential genetic factors. Genetic testing may be recommended in certain cases to rule out other genetic conditions that could cause similar symptoms.

Overall, due to the rare frequency of nonsyndromic aplasia cutis congenita and limited resources available, patient support and advocacy organizations play a vital role in providing information and support to individuals and families affected by this condition.

Causes

• Nonsyndromic aplasia cutis congenita is a rare congenital condition that causes a defect in the growth of skin on the scalp.
• The exact cause of this condition is not known, but it is thought to be related to genetic factors.
• There are several genetic causes that have been identified, including mutations in the TWIST1, MSX2, and IRF6 genes.
• Inheritance of nonsyndromic aplasia cutis congenita is typically autosomal dominant, meaning that an affected individual has a 50% chance of passing the condition on to their children.

Additional rare causes of aplasia cutis congenita can include teratogens, such as maternal use of antithyroid drugs during pregnancy, vascular accidents (such as amniotic bands), or other unidentified factors.

For more information on the causes of nonsyndromic aplasia cutis congenita, you can refer to the following resources:

1. PubMed: A search engine for scientific articles and references.
2. OMIM: A catalog of human genes and genetic disorders with detailed information on the condition.

Inheritance

Non-syndromic aplasia cutis congenita is a rare congenital condition that can cause areas of skin to be missing at birth. The specific cause of this condition is unknown, but it is believed to be genetic in nature.

There are various genes that have been associated with this condition, but they have not been identified in all cases. Additional genetic testing can be done to determine if a specific gene mutation is the cause of the aplasia cutis congenita in a patient.

The inheritance pattern of this condition is not well understood. It can occur sporadically, meaning it is not inherited from either parent. In other cases, it may be inherited in an autosomal dominant or autosomal recessive manner, meaning it is passed down from one or both parents.

Because this condition is rare, there is limited information available on its frequency and inheritance patterns. However, there are advocacy groups and resources available to support patients and provide additional information on the genetic causes of aplasia cutis congenita. These resources include the Online Mendelian Inheritance in Man (OMIM) database, which provides a catalog of genetic conditions and their associated genes, as well as articles and references on the topic available on PubMed.

Nonsyndromic aplasia cutis congenita, also known as congenital aplasia cutis or congenital scalp defect, is a rare condition characterized by the absence of skin in certain areas of the scalp. It is a congenital defect that can occur on the scalp, but can also affect other areas of the body. The condition is considered non-syndromic, meaning it does not involve additional abnormalities or conditions.

Causes of nonsyndromic aplasia cutis congenita are not fully understood, but it is believed to be related to genetic factors. Inheritance patterns for this condition are not clearly defined, but there is evidence suggesting that certain genes may play a role in its development.

Nonsyndromic aplasia cutis congenita commonly presents as a centrally located circular or oval patch of missing skin on the scalp. It can range in size from small, discrete lesions to large defects. The absence of skin can lead to complications such as infection and poor hair growth, and treatment may involve surgical repair or other means of intervention.

Patients diagnosed with nonsyndromic aplasia cutis congenita may benefit from additional support and resources. Advocacy groups, such as the National Organization for Rare Disorders (NORD) and the Aplasia Cutis Congenita International, can provide information, support, and connections to others affected by this condition.
