About this section


NIH Rare Diseases:41 Townes-brocks syndrome (tbs), or renal-ear-anal-radial (rear) syndrome, is a multiple malformation syndrome. characteristics are present at birth and vary from person to person. the most common characteristics include an absence of the anal opening (imperforate anus) and anomalies of the ears, hands, and feet. hearing loss, malformations of the genital-renal system, craniofacial malformations, and mental retardation may also be present. this condition is extremely rare. males and females are affected in equal numbers.  last updated: 9/5/2008

MalaCards based summary: Townes-Brocks Syndrome, also known as townes syndrome, is related to hemifacial microsomia and tuberculosis, and has symptoms including preauricular skin tag, preaxial hand polydactyly and triphalangeal thumb. An important gene associated with Townes-Brocks Syndrome is SALL1 (spalt-like transcription factor 1), and among its related pathways are Wnt Signaling Pathway and Adherens junction. The compounds arsenite and adpribose have been mentioned in the context of this disorder. Affiliated tissues include kidney, bone and uterus, and related mouse phenotypes are hearing/vestibular/ear and renal/urinary system.

Disease Ontology:9 An autosomal dominant disease that is characterized by imperforate anus, dysplastic ears often associated with sensorineural and/or conductive hearing impairment, and thumb malformations.

Genetics Home Reference:21 Townes-Brocks syndrome is a genetic condition that affects several parts of the body. The most common features of this condition are an obstruction of the anal opening (imperforate anus), abnormally shaped ears, and hand malformations that most often affect the thumb. Most people with this condition have at least two of these three major features.
