Osteogenesis imperfecta (OI) comprises a group of connective tissue disorders characterized by bone fragility and low bone mass. The disorder is clinically and genetically heterogeneous. OI type XII is an autosomal recessive form characterized by recurrent fractures, mild bone deformations, generalized osteoporosis, delayed teeth eruption, progressive hearing loss, no dentinogenesis imperfecta, and white sclerae (summary by Lapunzina et al., 2010).

Monosomy 5p, also known as Cri du chat syndrome, is a rare autosomal deletion syndrome characterized by a mewing cry (cri du chat) in infancy, multiple congenital anomalies, intellectual disability, microcephaly, and facial dysmorphism.

COG1-CDG is an extremely rare form of CDG syndrome (see this term) characterized clinically in the few cases reported to date by variable signs including microcephaly, growth retardation, psychomotor retardation and facial dysmorphism.

Perrault syndrome (PS) is characterized by the association of ovarian dysgenesis in females with sensorineural hearing impairment. In more recent PS reports, some authors have described neurologic abnormalities, notably progressive cerebellar ataxia and intellectual deficit.

Primary hypertrophic osteoarthropathy is a familial disorder characterized by digital clubbing and osteoarthropathy, with variable features of pachydermia, delayed closure of the fontanels, and congenital heart disease. Secondary hypertrophic osteoarthropathy, or pulmonary hypertrophic osteoarthropathy, is a different disorder characterized by digital clubbing secondary to acquired diseases, most commonly intrathoracic neoplasm (Uppal et al., 2008).Touraine et al. (1935) recognized pachydermoperiostosis as a familial disorder with 3 clinical presentations or forms: a complete form characterized by periostosis and pachydermia; an incomplete form with bone changes but without pachydermia; and a 'forme fruste' with pachydermia and minimal skeletal changes. Genetic HeterogeneityPHOAR2 (OMIM ) is caused by mutation in the SLCO2A1 gene (OMIM ) on chromosome 3q22.1-q22.2.Families with an autosomal dominant form of primary hypertrophic osteoarthropathy have also been reported (PHOAD ).

The main clinical features of CCD include persistently open skull sutures with bulging calvaria, hypoplasia or aplasia of the clavicles permitting abnormal facility in apposing the shoulders, wide pubic symphysis, short middle phalanx of the fifth fingers, dental anomalies, and often vertebral malformation.See {168550} for a discussion of the combination of cleidocranial dysplasia and parietal foramina. Pycnodysostosis (OMIM ) and mandibuloacral dysplasia (OMIM ) are disorders to be considered in the differential diagnosis of cleidocranial dysplasia. Acroosteolysis and bone sclerosis with tendency to fracture are differentiating features of pycnodysostosis.Mundlos (1999) provided a review of the clinical features of cleidocranial dysplasia and the molecular basis of this disorder.

Rhizomelic chondrodysplasia punctata (RCDP) is a peroxisomal disorder characterized by disproportionately short stature primarily affecting the proximal parts of the extremities, a typical facial appearance including a broad nasal bridge, epicanthus, high-arched palate, dysplastic external ears, and micrognathia, congenital contractures, characteristic ocular involvement, dwarfism, and severe mental retardation with spasticity. Biochemically, plasmalogen synthesis and phytanic acid alpha-oxidation are defective. Most patients die in the first decade of life. RCDP1 (OMIM ) is the most frequent form of RCDP (summary by Wanders and Waterham, 2005). Whereas RCDP1 is a peroxisomal biogenesis disorder (PBD), RCDP2 is classified as a single peroxisome enzyme deficiency (Waterham and Ebberink, 2012).For a discussion of genetic heterogeneity of rhizomelic chondrodysplasia punctata, see {215100}.
