Mondo Description Donnai-Barrow syndrome (DBS) is a rare, often severe, multiple congenital malformation syndrome with typical facial dysmorphism, ocular findings, hearing loss, agenesis of the corpus callosum, and variable intellectual disability. Congenital diaphragmatic hernia (CDH) and/or omphalocele are common.
Uniprot Description 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.
Disease Ontology Description An autosomal recessive disease 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 LRP2 gene on chromosome 2q31.
