Metaphyseal dysplasia without hypotrichosis

The cartilage-hair hypoplasia – anauxetic dysplasia (CHH-AD) spectrum disorders are a continuum that includes the following phenotypes: Metaphyseal dysplasia without hypotrichosis (MDWH). Cartilage-hair hypoplasia (CHH). Anauxetic dysplasia (AD). CHH-AD spectrum disorders are characterized by severe disproportionate (short-limb) short stature that is usually recognized in the newborn, and occasionally prenatally because of the short extremities. Other findings include joint hypermobility, fine silky hair, immunodeficiency, anemia, increased risk for malignancy, gastrointestinal dysfunction, and impaired spermatogenesis. The most severe phenotype, AD, has the most pronounced skeletal phenotype, may be associated with atlantoaxial subluxation in the newborn, and may include cognitive deficiency. The clinical manifestations of the CHH-AD spectrum disorders are variable, even within the same family. [from GeneReviews]

X-linked chondrodysplasia punctata 1

X-linked chondrodysplasia punctata 1 (CDPX1) is characterized by chondrodysplasia punctata (stippled epiphyses), brachytelephalangy (shortening of the distal phalanges), and nasomaxillary hypoplasia. Although most affected males have minimal morbidity and skeletal findings that improve by adulthood, some have significant medical problems including respiratory involvement, cervical spine stenosis and instability, mixed conductive and sensorineural hearing loss, and intellectual disability. [from GeneReviews]

Craniometaphyseal dysplasia, autosomal dominant

Autosomal dominant craniometaphyseal dysplasia (designated AD-CMD in this review) is characterized by progressive diffuse hyperostosis of cranial bones evident clinically as wide nasal bridge, paranasal bossing, widely spaced eyes with an increase in bizygomatic width, and prominent mandible. Development of dentition may be delayed and teeth may fail to erupt as a result of hyperostosis and sclerosis of alveolar bone. Progressive thickening of craniofacial bones continues throughout life, often resulting in narrowing of the cranial foramina, including the foramen magnum. If untreated, compression of cranial nerves can lead to disabling conditions such as facial palsy, blindness, or deafness (conductive and/or sensorineural hearing loss). In individuals with typical uncomplicated AD-CMD life expectancy is normal; in those with severe AD-CMD life expectancy can be reduced as a result of compression of the foramen magnum. [from GeneReviews]

Autosomal dominant osteopetrosis 1

The osteopetroses are a heterogeneous group of genetic disorders characterized by increased bone density due to impaired bone resorption by osteoclasts. Autosomal dominant osteopetrosis-1 (OPTA1) is characterized by generalized osteosclerosis most pronounced in the cranial vault. Patients are often asymptomatic, but some suffer from pain and hearing loss. It appears to be the only type of osteopetrosis not associated with an increased fracture rate (summary by Van Hul et al., 2002). Genetic Heterogeneity of Autosomal Dominant Osteopetrosis Autosomal dominant osteopetrosis-2 (OPTA2; 166600) is caused by mutation in the CLCN7 gene (602727) on chromosome 16p13. Autosomal dominant osteopetrosis-3 (OPTA3; 618107) is caused by mutation in the PLEKHM1 gene (611466) on chromosome 17q21. [from OMIM]

VACTERL with hydrocephalus

VACTERL describes a constellation of congenital anomalies, including vertebral anomalies, anal atresia, congenital cardiac disease, tracheoesophageal fistula, renal anomalies, radial dysplasia, and other limb defects; see 192350. Cases of familial VACTERL with hydrocephalus (H) have been reported with suggestion of autosomal recessive or X-linked inheritance (see 314390). Other patients thought to have VACTERL-H, including 2 unrelated infants reported by Porteous et al. (1992), had been found to have Fanconi anemia (see 227650). Porteous et al. (1992) suggested that chromosomal breakage studies should be performed in all cases of VACTERL/VACTERL-H to rule out Fanconi anemia. Alter et al. (2007) noted that a VATER phenotype had been reported in Fanconi anemia of complementation groups A (227650), C (227645), D1 (605724), E (600901), F (603467), and G (614082). X-linked VACTERL-H is also associated with mutations in the FANCB gene (300515). [from OMIM]

VACTERL association, X-linked, with or without hydrocephalus

VACTERL is an acronym for vertebral anomalies (similar to those of spondylocostal dysplasia), anal atresia, cardiac malformations, tracheoesophageal fistula, renal anomalies (urethral atresia with hydronephrosis), and limb anomalies (hexadactyly, humeral hypoplasia, radial aplasia, and proximally placed thumb; see 192350). Some patients may have hydrocephalus, which is referred to as VACTERL-H (Briard et al., 1984). [from OMIM]

Cerebrooculofacioskeletal syndrome 4

Cerebrooculofacioskeletal syndrome-4 (COFS4) is a severe autosomal recessive disorder characterized by growth retardation, dysmorphic facial features, arthrogryposis, and neurologic abnormalities. Cellular studies show a defect in both transcription-coupled and global genome nucleotide excision repair (TC-NER and GG-NER) (summary by Jaspers et al., 2007 and Kashiyama et al., 2013). For a discussion of genetic heterogeneity of cerebrooculofacioskeletal syndrome, see 214150. [from OMIM]

3MC syndrome 2

The term '3MC syndrome' encompasses 4 rare autosomal recessive disorders that were previously designated the Carnevale, Mingarelli, Malpuech, and Michels syndromes, respectively. The main features of these syndromes are facial dysmorphism that includes hypertelorism, blepharophimosis, blepharoptosis, and highly arched eyebrows, which are present in 70 to 95% of cases. Cleft lip and palate, postnatal growth deficiency, cognitive impairment, and hearing loss are also consistent findings, occurring in 40 to 68% of cases. Craniosynostosis, radioulnar synostosis, and genital and vesicorenal anomalies occur in 20 to 30% of cases. Rare features include anterior chamber defects, cardiac anomalies, caudal appendage, umbilical hernia (omphalocele), and diastasis recti (summary by Rooryck et al., 2011). For a discussion of genetic heterogeneity of 3MC syndrome, see 3MC1 (257920). [from OMIM]

Ossification of the posterior longitudinal ligament of the spine

Ossification of the posterior longitudinal ligament of the spine (OPLL) is a common degenerative spinal disorder that causes severe neurologic dysfunction in middle-aged and elderly populations. This ectopic ossification results in compression of the spinal cord and nerve root by the ossified ligament. Histologic studies of OPLL suggest that OPLL develops through a process of endochondral ossification (summary by Nakajima et al., 2016). [from OMIM]

Osebold-Remondini syndrome

The Osebold-Remondini syndrome is a bone dysplasia with mesomelic shortness of limbs and, hence, shortness of stature, absence or hypoplasia of second phalanges with synostosis of the remaining phalanges, carpal and tarsal coalitions, and apparently no other anomalies (summary by Opitz and Gilbert, 1985). See 602875 for a discussion of genetic heterogeneity of autosomal recessive acromesomelic dysplasia. [from OMIM]

Holoprosencephaly-radial heart renal anomalies syndrome

This syndrome has characteristics of holoprosencephaly, predominantly radial limb deficiency (absent thumbs, phocomelia), heart defects, kidney malformations and absence of gallbladder. It has been described in two families (with at least seven affected persons). Variable manifestations include vertebral anomalies, cleft lip/palate, microphthalmia, absent nose, dysplastic ears, hearing loss, colobomas of the iris and retina and/or bifid uvula. Inheritance is likely to be autosomal dominant with variable expressivity. [from SNOMEDCT_US]

Intradural spinal arachnoid cyst

Spinal intradural arachnoid cysts are cerebrospinal fluid -filled sacs that are located between the spinal cord and the arachnoid membrane (one of the three membranes that cover the brain and spinal cord). The signs and symptoms of the condition vary based on the size and location of the cysts. Some affected people may have no suspicious symptoms while others experience progressive back and leg pain; tingling or numbness in the hands or feet; weakness of the legs; and involuntary muscle spasms (spasticity) that result in slow, stiff movements of the legs. When present, symptoms usually occur when the cysts compress the spinal cord or other nearby nerves. Spinal intradural arachnoid cysts are often present at birth and arecaused by developmental abnormalities in the spinal cord that occur during the pregnancy. They can also result from a previous infection or injury and develop later in life. Although there is disagreement in the medical community regarding when to treat spinal intradural arachnoid cysts, the need for treatment generally depends on the size and location of the cyst and whether or not it is causing symptoms. When indicated, the cysts are typically treated with surgery. [from MONDO]
