The Verloes-David-Pfeiffer mesomelia-synostoses syndrome is an autosomal dominant form of mesomelic dysplasia comprising typical acral synostoses combined with ptosis, hypertelorism, palatal abnormality, congenital heart disease, and ureteral anomalies (summary by Isidor et al., 2009). Mesomelia and synostoses are also cardinal features of the Kantaputra type of mesomelic dysplasia (156232). [from OMIM]

Heart and brain malformation syndrome (HBMS) is a severe autosomal recessive multiple congenital anomaly syndrome characterized by profoundly delayed psychomotor development, dysmorphic facial features, microphthalmia, cardiac malformations, mainly septal defects, and brain malformations, including Dandy-Walker malformation (summary by Shaheen et al., 2016). Homozygous mutation in the SMG9 gene can also cause neurodevelopmental disorder with intention tremor, pyramidal signs, dyspraxia, and ocular anomalies (NEDITPDO; 619995), a less severe neurodevelopmental disorder. [from OMIM]

Common variable immunodeficiency-10 (CVID10) is an autosomal dominant primary immunodeficiency characterized by childhood-onset of recurrent infections, hypogammaglobulinemia, and decreased numbers of memory and marginal zone B cells. Some patients may develop autoimmune features and have circulating autoantibodies. An unusual feature is central adrenal insufficiency (summary by Chen et al., 2013). For a general description and a discussion of genetic heterogeneity of common variable immunodeficiency, see CVID1 (607594). [from OMIM]

Mesomelic dysplasia is shortening of the middle or intermediate portion of the limb. In the upper limb this is relative shortening of the radius and ulna, in the lower limb the tibia and fibula. [from SNOMEDCT_US]

The presence of multiple congenital malformations in a patient. [from NCI]

Marinesco-Sjögren syndrome (MSS) is characterized by cerebellar ataxia with cerebellar atrophy, dysarthria, nystagmus, early-onset (not necessarily congenital) cataracts, myopathy, muscle weakness, and hypotonia. Additional features may include psychomotor delay, hypergonadotropic hypogonadism, short stature, and various skeletal abnormalities. Children with MSS usually present with muscular hypotonia in early infancy; distal and proximal muscular weakness is noticed during the first decade of life. Later, cerebellar findings of truncal ataxia, dysdiadochokinesia, nystagmus, and dysarthria become apparent. Motor function worsens progressively for some years, then stabilizes at an unpredictable age and degree of severity. Cataracts can develop rapidly and typically require lens extraction in the first decade of life. Although many adults have severe disabilities, life span in MSS appears to be near normal. [from GeneReviews]

A disease characterized by abnormal union between adjacent bones or parts of a single bone formed by osseous material, such as ossified connecting cartilage or fibrous tissue. [from MONDO]

A defect in ossification of bone. [from NCI]

Any disorder of development of the bone. [from NCI]

Limb shortening because of underdevelopment of one or more bones of the extremities. [from HPO]

Shortening of the middle parts of the limbs (forearm and lower leg) in relation to the upper and terminal segments. [from HPO]

Autosomal recessive spondylometaphyseal dysplasia, Mégarbané type is a rare, primary bone dysplasia characterized by intrauterine growth retardation, pre- and postnatal disproportionate short stature with short, rhizomelic limbs, facial dysmorphism, a short neck and small thorax. Hypotonia, cardiomegaly and global developmental delay have also been associated. Several radiographic findings have been reported, including ribs with cupped ends, platyspondyly, square iliac bones, horizontal and trident acetabula, hypoplastic ischia, and delayed epiphyseal ossification. [from ORDO]

This syndrome is an isolated upper limb mesomelic dysplasia. It has been described in four patients from two unrelated families (a man and his daughter, and a Lebanese man and his son). Patients present with ulnar hypoplasia with severe radial bowing, but normal stature. The mode of transmission is likely to be autosomal dominant with variable expressivity. [from ORDO]

A rare primary bone dysplasia with characteristics of micromelia with rhizomelic shortening, metaphyseal widening of the long bones, brachydactyly, small scapula, micrognathia and thoracic insufficiency requiring tracheostomy and ventilation, severe myopia and sensorineural hearing loss. Further dysmorphic craniofacial features include frontal bossing, proptosis, epicanthal folds, short nose, flat nasal bridge, anteverted nares, midfacial retrusion and cleft palate. [from SNOMEDCT_US]

Multiple synostoses syndrome is characterized by multiple joint fusions, usually commencing in the hands, conductive deafness, and characteristic facial features, including a broad, tubular-shaped nose and a thin upper vermilion. Other features include brachydactyly, hypoplastic or absent middle phalanges, radial head dislocation, and pectus carinatum (summary by Takahashi et al., 2001). Genetic Heterogeneity of Multiple Synostoses Syndrome Other forms of multiple synostoses syndrome include SYNS2 (610017), caused by mutation in the GDF5 gene (601146) on chromosome 20q11; SYNS3 (612961), caused by mutation in the FGF9 gene (600921) on chromosome 13q12; and SYNS4 (617898), caused by mutation in the GDF6 gene (601147) on chromosome 8q22. [from OMIM]
