Summaries for Donnai-Barrow Syndrome

MedlinePlus Genetics : 43 Donnai-Barrow syndrome is an inherited disorder that affects many parts of the body. This disorder is characterized by unusual facial features, including prominent, wide-set eyes with outer corners that point downward; a short bulbous nose with a flat nasal bridge; ears that are rotated backward; and a widow's peak hairline.Individuals with Donnai-Barrow syndrome have severe hearing loss caused by abnormalities of the inner ear (sensorineural hearing loss). In addition, they often experience vision problems, including extreme nearsightedness (high myopia), detachment or deterioration of the light-sensitive tissue in the back of the eye (the retina), and progressive vision loss. Some have a gap or split in the colored part of the eye (iris coloboma).In almost all people with Donnai-Barrow syndrome, the tissue connecting the left and right halves of the brain (corpus callosum) is underdeveloped or absent. Affected individuals may also have other structural abnormalities of the brain. They generally have mild to moderate intellectual disability and developmental delay.People with Donnai-Barrow syndrome may also have a hole in the muscle that separates the abdomen from the chest cavity (the diaphragm), which is called a congenital diaphragmatic hernia. This potentially serious birth defect allows the stomach and intestines to move into the chest and possibly crowd the developing heart and lungs. An opening in the wall of the abdomen (an omphalocele) that allows the abdominal organs to protrude through the navel may also occur in affected individuals. Occasionally people with Donnai-Barrow syndrome have abnormalities of the intestine, heart, or other organs.

MalaCards based summary : Donnai-Barrow Syndrome, also known as faciooculoacousticorenal syndrome, is related to proteinuria, chronic benign and lowe oculocerebrorenal syndrome, and has symptoms including unspecified visual loss An important gene associated with Donnai-Barrow Syndrome is LRP2 (LDL Receptor Related Protein 2), and among its related pathways/superpathways are Hedgehog signaling pathway and Metabolism of water-soluble vitamins and cofactors. Affiliated tissues include eye, heart and retina, and related phenotypes are intellectual disability and global developmental delay

Disease Ontology : 12 A syndrome that is characterized by facial and ocular abnormalities, sensorineural hearing loss, agenesis of the corpus callosum, variable intellectual disability, and proteinuria that has material basis in homozygous or compound heterozygous mutation in the LDL receptor related protein 2 gene (LRP2) on chromosome 2q31.

GARD : 20 Donnai Barrow syndrome is an inherited disorder that affects many parts of the body. People with this condition generally have characteristic facial features, severe sensorineural hearing loss, vision problems and an absent or underdeveloped corpus callosum (the tissue connecting the left and right halves of the brain). Other features may include diaphragmatic hernia, omphalocele, and/or other abnormalities of the intestine or heart. Affected people often have mild to moderate intellectual disability and developmental delay. Donnai Barrow syndrome is caused by changes ( mutations ) in the LRP2 gene and is inherited in an autosomal recessive manner. Treatment of this condition is based on the signs and symptoms present in each person but may include hearing aids and/or cochlear implants for hearing loss, corrective lenses for vision problems and surgery for certain physical abnormalities.

OMIM® : 57 The faciooculoacousticorenal (FOAR) syndrome was first described as comprising facial anomalies, ocular anomalies, sensorineural hearing loss, and proteinuria. Facial features include prominent brow, short nose, and hypertelorism, and ocular anomalies include myopia, iris hypoplasia, and/or retinal detachment (Regenbogen and Coscas, 1985). Donnai-Barrow syndrome (DBS) was first described as a distinct disorder characterized by diaphragmatic hernia, exomphalos, absent corpus callosum, myopia, and sensorineural deafness. The classic distinguishing features between the 2 disorders were presence of proteinuria and absence of diaphragmatic hernia and corpus callosum anomalies in FOAR (Donnai and Barrow, 1993). However, early reports noted that the 2 disorders shared many phenotypic features and may be identical (e.g., Devriendt et al., 1998). Although there is variability in the expression of some features (e.g., agenesis of the corpus callosum and proteinuria), the disorders are now considered to represent the same entity (Kantarci et al., 2007). (222448) (Updated 05-Apr-2021)

KEGG : 36 Donnai-Barrow syndrome is a rare autosomal recessive disorder of multiple anomalies resulting from mutations in the LRP2 gene. It is characterized by agenesis of the corpus callosum, typical craniofacial features (ocular hypertelorism, enlarged fontanelle), ophthalmological abnormalities (high myopia, iris stromal hypoplasia), severe sensorineural deafness, congenital diaphragmatic hernia, and proteinuria. The diagnosis is confirmed by detection of mutations in LRP2.

UniProtKB/Swiss-Prot : 72 Donnai-Barrow syndrome: Rare autosomal recessive disorder characterized by major malformations including agenesis of the corpus callosum, congenital diaphragmatic hernia, facial dysmorphology, ocular anomalies, sensorineural hearing loss and developmental delay. The FOAR syndrome was first described as comprising facial anomalies, ocular anomalies, sensorineural hearing loss, and proteinuria. DBS and FOAR were first described as distinct disorders but the classic distinguishing features between the 2 disorders were presence of proteinuria and absence of diaphragmatic hernia and corpus callosum anomalies in FOAR. Early reports noted that the 2 disorders shared many phenotypic features and may be identical. Although there is variability in the expression of some features (e.g., agenesis of the corpus callosum and proteinuria), DBS and FOAR are now considered to represent the same entity.
