Disease:Defects in SALL4 are the cause of Duane-radial ray syndrome (DRRS) [MIM:607323]; also known as Okihiro syndrome. DRRS is a disorder characterized by the association of forearm malformations with Duane retraction syndrome. ,Disease:Defects in SALL4 are the cause of IVIC syndrome [MIM:147750]. IVIC syndrome is an autosomal dominant condition characterized by upper limbs anomalies (radial ray defects , carpal bones fusion) , extraocular motor disturbances , congenital bilateral non-progressive mixed hearing loss. Other less consistent malformations include heart involvement , mild thrombocytopenia and leukocytosis (before age 50) , shoulder girdle hypoplasia , imperforate anus , kidney malrotation or rectovaginal fistula. The IVIC syndrome is an allelic disorder of Duane-radial ray syndrome (DRRS) with a similar phenotype. ,Function:Probable transcription factor. ,similarity:Belongs to the sal C2H2-type zinc-finger protein family. ,similarity:Contains 7 C2H2-type zinc fingers. ,subunit:Interacts with NANOG. ,tissue specificity:Expressed in testis. ,
