'''PURA syndrome''' is a rare genetic disorder characterized by developmental delay, hypotonia, and neurological abnormalities. It is caused by mutations in the [[PURA gene]], which plays a crucial role in the development and function of the nervous system. The condition is inherited in an [[autosomal dominant]] pattern, meaning a single copy of the altered gene in each cell is sufficient to cause the disorder.
== Genetics ==
== Genetics ==
The [[PURA gene]] provides instructions for making a protein that is involved in the regulation of gene expression and is crucial for normal brain development. Mutations in this gene lead to the symptoms observed in PURA Syndrome. These mutations are typically de novo, meaning they occur spontaneously and are not inherited from the parents.
PURA syndrome is associated with mutations in the [[PURA gene]], located on chromosome 5. The gene encodes the purine-rich element binding protein A, which is involved in the regulation of [[DNA replication]] and [[RNA transcription]]. Mutations in this gene disrupt normal neurological development, leading to the symptoms observed in affected individuals.

* '''[[Hypotonia]]''': Low muscle tone is a common feature, leading to difficulties with movement and posture.
* [[Hypotonia]] (reduced muscle tone)

A rare genetic disorder affecting neurological development


PURA syndrome is a rare genetic disorder characterized by developmental delay, hypotonia, and neurological abnormalities. It is caused by mutations in the PURA gene, which plays a crucial role in the development and function of the nervous system. The condition is inherited in an autosomal dominant pattern, meaning a single copy of the altered gene in each cell is sufficient to cause the disorder.

Genetics[edit]

PURA syndrome is associated with mutations in the PURA gene, located on chromosome 5. The gene encodes the purine-rich element binding protein A, which is involved in the regulation of DNA replication and RNA transcription. Mutations in this gene disrupt normal neurological development, leading to the symptoms observed in affected individuals.

Clinical Features[edit]

Individuals with PURA syndrome typically present with a range of neurological and developmental issues. Common features include:

Diagnosis[edit]

Diagnosis of PURA syndrome is based on clinical evaluation and genetic testing. Whole exome sequencing or targeted gene panels can identify mutations in the PURA gene, confirming the diagnosis.

Management[edit]

There is currently no cure for PURA syndrome, and treatment is symptomatic and supportive. Management strategies may include:

Prognosis[edit]

The prognosis for individuals with PURA syndrome varies depending on the severity of symptoms. While some individuals may achieve developmental milestones with support, others may have significant lifelong challenges.
