Worth syndrome: Difference between revisions

Revision as of 05:48, 16 February 2025

A genetic disorder characterized by a combination of symptoms including intellectual disability and distinctive facial features.

Overview

Worth syndrome is a rare genetic disorder that is primarily characterized by intellectual disability, distinctive facial features, and skeletal abnormalities. It is inherited in an autosomal dominant pattern, meaning that a single copy of the altered gene in each cell is sufficient to cause the disorder.

Genetics

Worth syndrome is caused by mutations in a specific gene, which is inherited in an autosomal dominant manner. This means that an affected individual has a 50% chance of passing the mutated gene to each of their children. The specific gene involved in Worth syndrome has not been definitively identified, but it is known to affect the development of the skeletal system and nervous system.

Clinical Features

Individuals with Worth syndrome typically present with a range of clinical features, including:

Intellectual disability: Varying degrees of intellectual disability are common in individuals with Worth syndrome.
Facial dysmorphism: Distinctive facial features may include a broad forehead, wide-set eyes, and a flat nasal bridge.
Skeletal abnormalities: These may include osteosclerosis, which is an abnormal hardening of bone, and other bone malformations.

Diagnosis

The diagnosis of Worth syndrome is primarily based on clinical evaluation and the identification of characteristic features. Genetic testing can confirm the diagnosis by identifying mutations in the gene associated with the disorder.

Management

There is no cure for Worth syndrome, and treatment is focused on managing the symptoms and improving the quality of life for affected individuals. This may include:

Educational support: Special education programs can help individuals with intellectual disabilities achieve their full potential.
Physical therapy: To address skeletal abnormalities and improve mobility.
Regular monitoring: Ongoing medical evaluations to monitor the progression of symptoms and manage complications.

Prognosis

The prognosis for individuals with Worth syndrome varies depending on the severity of symptoms. With appropriate management and support, many individuals can lead fulfilling lives.

-==Cause and Genetics==
+==Overview==
+[[Worth syndrome]] is a rare [[genetic disorder]] that is primarily characterized by [[intellectual disability]], distinctive [[facial features]], and [[skeletal abnormalities]]. It is inherited in an [[autosomal dominant]] pattern, meaning that a single copy of the altered gene in each cell is sufficient to cause the disorder.
-Worth syndrome is caused by a [[mutation]] in the [[LRP5]] gene, located on human [[chromosome]] [[chromosome 11 (human)|11q13.4]].<ref name=wad/><ref>{{OMIM|603506}}</ref> The disorder is inherited in an autosomal dominant fashion.<ref name=omim/> This indicates that the defective gene responsible for a disorder is located on an [[autosome]] (chromosome 11 is an autosome), and only one copy of the defective gene is sufficient to cause the disorder, when inherited from a parent who has the disorder.

-==History==
+==Prognosis==
-The condition was first reported by [[H. M. Worth]] in 1966. In 1977, two [[physician|doctors]], R.J. Gorlin and L. Glass, distinguished the syndrome from [[van Buchem disease]]. In 1987 a group of [[Spain|Spanish]] doctors pointed out that the condition may not be [[benign]], and may sometimes cause [[nerve]] damage.<ref name=omim/>
+The prognosis for individuals with Worth syndrome varies depending on the severity of symptoms. With appropriate management and support, many individuals can lead fulfilling lives.
