Introduction
Townes–Brocks Syndrome is a rare genetic disorder characterized by imperforate anus, dysplastic ears, and thumb malformations․ It affects various parts of the body, with mutations in the SALL1 gene playing a key role in its development․
Overview of Townes-Brocks Syndrome
Townes–Brocks Syndrome is a rare autosomal dominant disorder characterized by imperforate anus, dysplastic ears with hearing impairment, and thumb malformations․ The condition, caused by mutations in the SALL1 gene, may also present with renal, urogenital, and heart malformations․ Although intellectual development is typically normal, affected individuals may exhibit other associated features affecting multiple organs․
Clinical Features
Townes–Brocks Syndrome presents with a triad of imperforate anus, dysplastic ears with hearing impairment, and thumb malformations․ Additional malformations may include renal, urogenital, and heart abnormalities․ Mutations in the SALL1 gene play a crucial role in the development of this rare disorder․
Triad of Symptoms
Townes–Brocks Syndrome is defined by the presence of imperforate anus, dysplastic ears often associated with hearing impairment, and thumb malformations․ Individuals with this rare genetic disorder may also exhibit additional malformations affecting various organs, such as the kidneys and heart․ The condition is primarily attributed to mutations in the SALL1 gene, leading to its characteristic triad of symptoms․
Other Associated Malformations
In addition to the characteristic triad of symptoms, individuals with Townes–Brocks Syndrome may present with renal, urogenital, and heart abnormalities․ The condition is known for its variable expression, with manifestations such as external ear anomalies, hearing loss, preaxial polydactyly, and renal abnormalities․ While most individuals with this syndrome have normal intelligence, some rare cases exhibit concurrent endocrine abnormalities․
Genetics
At least 75 mutations in the SALL1 gene have been identified in individuals with Townes-Brocks Syndrome․ This rare disorder is typically characterized by imperforate anus, abnormally shaped ears, and hand malformations․ The specific effects of these mutations on the condition’s features remain uncertain․
SALL1 Gene Mutations
