Causes
The proximal 18q deletion syndrome is a rare genetic condition that is caused by a deletion on the long arm of chromosome 18. This deletion can vary in size and can involve different regions of the chromosome.
Testing for the condition can be done using a variety of methods, including chromosomal microarray analysis and fluorescence in situ hybridization (FISH) testing. These tests can help to identify the specific location and extent of the deletion in a patient’s genome.
The exact cause of proximal 18q deletion syndrome is not fully understood. However, it is believed to be a result of random, spontaneous genetic changes that occur during early development. In some cases, the condition may be inherited from a parent who carries the deletion, but this is rare.
There have been several scientific articles published on the causes of the syndrome. Some of these articles support the idea that certain genes within the deleted region are associated with the development of the condition. Additional research is needed to fully understand the role of these genes in the proximal 18q deletion syndrome.
It is important to note that proximal 18q deletion syndrome is a rare disorder, and the frequency of the condition is not well documented. Information on the prevalence of the syndrome can be found in resources such as the Online Mendelian Inheritance in Man (OMIM) catalog, scientific articles, and other genetic databases.
For individuals and families affected by proximal 18q deletion syndrome, there are several advocacy organizations and support groups available to provide information, resources, and support.
