Summaries for Ivic Syndrome

NIH Rare Diseases : 52 The following summary is from Orphanet , a European reference portal for information on rare diseases and orphan drugs. Orpha Number: 2307 Definition IVIC syndrome is a very rare genetic malformation syndrome characterized by upper limb anomalies (radial ray defects, carpal bone fusion), extraocular motor disturbances, and congenital bilateral non-progressive mixed hearing loss . Epidemiology Prevalence of IVIC is not known. To date, four affected families from Venezuela, Italy, Hungary, and Turkey (discordant monozygotic twins ) have been described. Clinical description Asymmetrical upper limbs are a characteristic clinical manifestation. Thumb involvement is the most typical clinical manifestation and can range from absence or hypoplasia to the presence of a triphalangic thumb. Other upper limb anomalies include radial ray defects and carpal bone fusion. Upper limbs may be severely malformed. Extraocular motor disturbances and hearing loss of variable severity have also been reported. Some affected individuals have been reported to have mild thrombocytopenia , leukocytosis, shoulder girdle hypoplasia, cardiac involvement, kidney malrotation, intermediate anorectal malformation (see this term), or rectovaginal fistula. The clinical presentation is highly variable but lower limbs are normal. There have been reports of sudden death. Etiology The syndrome has been linked to mutations in the SALL4 gene (20q13.2) encoding a transcription factor involved in the maintenance and self-renewal of embryonic and hematopoietic stem cells . Okihiro syndrome (see this term) is a disorder allelic to IVIC syndrome. Genetic counseling IVIC syndrome is inherited in an autosomal dominant manner. Genetic counseling should be offered to affected families, informing them of the 50% chance of offspring inheriting the disease-causing mutation and therefore being affected with the syndrome.

MalaCards based summary : Ivic Syndrome, also known as oculootoradial syndrome, is related to cystic fibrosis and strabismus, and has symptoms including ophthalmoplegia An important gene associated with Ivic Syndrome is SALL4 (Spalt Like Transcription Factor 4). Affiliated tissues include bone, kidney and heart, and related phenotypes are hearing impairment and joint stiffness

Disease Ontology : 12 A syndrome characterized by radial ray defect of variable severity, mixed congenital hearing loss, mild thrombocytopenia, and external ophthalmoplegia that has material basis in heterozygous mutation in SALL4 on chromosome 20q13.2.

KEGG : 36 The IVIC syndrome is an autosomal dominant complex pleiotropic syndrome with radial ray hypoplasia, hearing impairment, external ophthalmoplegia, and thrombocytopenia. It is caused by mutations in the SALL4. SALL4 encodes a transcription factor with a wide expression in early embryogenesis, and later expression restricted to adult testis and ovary.

UniProtKB/Swiss-Prot : 73 Oculootoradial syndrome: 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.
