Summaries for Boomerang Dysplasia

GARD : 20 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs. Orpha Number: 1263 Definition Boomerang dysplasia (BD) is a rare lethal skeletal dysplasia characterized by severe short-limbed dwarfism, dislocated joints, club feet, distinctive facies and diagnostic x-ray findings of underossified and dysplastic long tubular bones, with a boomerang-like bowing. Epidemiology The prevalence of BD is unknown. Clinical description Affected neonates are stillborn or die rapidly after birth and present clinically with severe short-limbed dwarfism, dislocated hip, knee and elbow joints, club feet and proviso born alive have severe cardio respiratory failure. Facial dysmorphism includes midface hypoplasia and cleft palate. Boomerang dysplasia clinically differs from AOI and AOIII because of the boomerang shaped bowing of the femur and occasionally observed encephalocele and omphalocele. Etiology BD results from missense mutations or small in-frame deletions in the FLNB gene reported in exons 2-5, normally expected to translate full length but biochemically abnormal filamin B protein. Diagnostic methods Diagnosis can be confirmed from skeletal radiographs, chondro-osseous histopathology and genetic testing. Distinctive radiographic findings are similar to AOI but, BD presents with a more severe deficiency in mineralization, with non-ossification of certain segments of limbs and vertebrates, and a boomerang-like shape of some long tubular bones. Differential diagnosis Comprises other skeletal dysplasias with severe short-limbed dwarfism such as achondrogenesis, campomelic dysplasia, Ellis-van Creveld syndrome, achondroplasia, metatropic dysplasia, Roberts syndrome, short rib- polydactyly syndrome and thanatophoric dysplasia. Additional differential diagnosis includes diseases associated with impaired ossification such achondrogenesis, hypophosphatasia, and osteogenesis imperfecta (see these terms). Antenatal diagnosis The prenatal diagnosis of BD is difficult to ascertain by ultrasound. Ultrasound shows thoracic hypoplasia, limb shortening, delayed ossification of spine and appendicular segments and possibly joint dislocations, similar to AOI and AOIII. Boomerang-shape morphology some long tubular bones may be diagnosed prenatally by 3D- CT scan. Prognosis Prognosis is poor, as the condition is lethal in utero.

MalaCards based summary : Boomerang Dysplasia, also known as boomd, is related to larsen syndrome and atelosteogenesis. An important gene associated with Boomerang Dysplasia is FLNB (Filamin B), and among its related pathways/superpathways are MAPK signaling pathway and Focal adhesion. Affiliated tissues include bone, and related phenotypes are abnormality of tibia morphology and narrow chest

Disease Ontology : 12 An osteochondrodysplasia that is characterized by severe dwarfism, dislocated joints, club feet, distinctive facies and dysplastic tubular bones with boomerang-like bowing, has material basis in heterozygous mutation in the FLNB gene on chromosome 3p14.

MedlinePlus Genetics : 43 Boomerang dysplasia is a disorder that affects the development of bones throughout the body. Affected individuals are born with inward- and upward-turning feet (clubfeet) and dislocations of the hips, knees, and elbows. Bones in the spine, rib cage, pelvis, and limbs may be underdeveloped or in some cases absent. As a result of the limb bone abnormalities, individuals with this condition have very short arms and legs. Pronounced bowing of the upper leg bones (femurs) gives them a "boomerang" shape.Some individuals with boomerang dysplasia have a sac-like protrusion of the brain (encephalocele). They may also have an opening in the wall of the abdomen (an omphalocele) that allows the abdominal organs to protrude through the navel. Affected individuals typically have a distinctive nose that is broad with very small nostrils and an underdeveloped partition between the nostrils (septum).Individuals with boomerang dysplasia typically have an underdeveloped rib cage that affects the development and functioning of the lungs. As a result, affected individuals are usually stillborn or die shortly after birth from respiratory failure.

OMIM® : 57 Bommerang dysplasia is a perinatal lethal osteochondrodysplasia characterized by absence or underossification of the limb bones and vertebrae (summary by Bicknell et al., 2005). (112310) (Updated 20-May-2021)

KEGG : 36 Boomerang dysplasia (BD) is a perinatal lethal osteochondrodysplasia. Typical symptoms include micromelia with diminished ossification, and a characteristic bowed and boomerang like aspect of the long tubular bones. BD is caused by mutations in FLNB, the gene encoding the actin binding cytoskeletal protein, filamin B.

UniProtKB/Swiss-Prot : 72 Boomerang dysplasia: A perinatal lethal osteochondrodysplasia characterized by absence or underossification of the limb bones and vertebrae. Patients manifest dwarfism with short, bowed, rigid limbs and characteristic facies. Boomerang dysplasia is distinguished from atelosteogenesis on the basis of a more severe defect in mineralization, with complete absence of ossification in some limb elements and vertebral segments.
