Potocki-Shaffer syndrome (PSS) is a rare genetic disorder associated with deletions on chromosome 11p11.2. This condition is also known as Potocki-Lupski syndrome. PSS was first described in 1996 by Potocki and Shaffer, who identified the deletion of the PHF21A gene as the cause. This syndrome is characterized by a range of developmental and physical abnormalities, including cognitive impairments, skeletal abnormalities, and facial dysmorphisms.

The frequency of PSS is not well established, but it is considered to be a rare condition. The exact cause of PSS is not fully understood, but research suggests that the deletion of the PHF21A gene may disrupt the normal development of various body systems, leading to the symptoms associated with this syndrome. It is inherited in an autosomal dominant manner, which means that a person who has the deletion has a 50% chance of passing it on to their offspring.

ClinicalTrials.gov has a searchable database of ongoing clinical studies on PSS, which can provide more information on the research and studies being conducted on this condition. PubMed is another valuable resource for finding scientific articles and studies on PSS. The Online Mendelian Inheritance in Man (OMIM) database provides detailed information on the genes associated with PSS and other rare genetic diseases.

For patients and families affected by PSS, there are also support resources available. The Center for Rare Genetic Diseases provides information and support for individuals and families affected by rare genetic conditions. Genetic testing can be done to confirm a diagnosis of PSS. It is important for individuals with a family history of the syndrome or those showing symptoms to seek testing and counseling from a geneticist or genetic counselor.

In conclusion, Potocki-Shaffer syndrome is a rare genetic condition associated with deletions on chromosome 11p11.2. It is characterized by a range of developmental and physical abnormalities. Ongoing research and clinical trials are being conducted to learn more about the causes and treatment options for this condition. Genetic testing and support resources are available for individuals and families affected by PSS.
