SALL1: Transcriptional repressor involved in organogenesis. Defects in SALL1 are the cause of Townes-Brocks syndrome (TBS). TBS is a rare, autosomal dominant malformation syndrome with a combination of imperforate anus, triphalangeal and supernumerary thumbs, malformed ears and sensorineural hearing loss. Some individuals with SALL1 mutations manifest a phenotype overlapping with TBS and bronchio-oto-renal syndrome. Clinical features include dysplastic ears, hypoplastic kidneys with impaired renal function, gastroesophageal reflux, hypermetropia, hypospadias, and mild developmental delay. Affected individuals lack the characteristic anal or hand malformations of TBS. Belongs to the sal C2H2-type zinc-finger protein family. 2 isoforms of the human protein are produced by alternative splicing.
