SHORT syndrome is a very rare genetic disease that is distinguished by the simultaneous presence of a short stature, prominent hyperextensibility of the joints, inguinal hernia, ocular abnormalities, lipodystrophy and a delay in tooth eruption. The diagnosis can be made only after a thorough physical examination that will identify all signs and symptoms, as genetic testing is scarcely available.
Presentation
Since its initial description more than 50 years ago, SHORT syndrome is an acronym composed of the five main clinical characteristics encountered in the few patients reported in the medical literature so far [1] [2] [3] [4]:
- Short stature - Although up to one-third of cases present in the lower range of normal body height, short stature and a small height relative to the gestational age is a defining feature of this syndrome [5]. In addition to intrauterine growth retardation (IGR), which is readily noted, microcephaly, delayed bone age, and gracile long bones are observed in the majority of cases [5].
- Hyperextensibility of joints and/or hernias - Present only in a minority of individuals (around 35%).
- Ocular depression and Rieger anomaly - Dysgenesis of the anterior chamber, often described in the literature as the Rieger anomaly, is a cardinal feature and is seen in 100% of SHORT syndrome patients [1] [3] [4] [6].
- Tooth eruption delay - Similarly to ocular depression, delay in the eruption of teeth is confirmed in almost every patient suffering from SHORT syndrome [3] [4] [6].
In addition to the above mentioned signs and symptoms, several other features are described in this small group of individuals: facial anomalies (micrognathia, a triangular appearance of the face, megalocornea, anteverted ears, and hypoplasia of the nasal alae), lipodystrophy (near complete absence of subcutaneous fat), insulin resistance and eventual development of diabetes mellitus, hearing impairment, clinodactyly, and normal intellectual development, which may be particularly important in distinguishing SHORT syndrome from many other genetic diseases that affect mental development [1] [6] [7].

What is Idiopathic Short Stature? Idiopathic Short Stature (also known as ISS) is a big name for children who are short with no known cause. ISS is a problem that can be present in both boys and girls. [magicfoundation.org]
Idiopathic, where there is no identifiable cause of short stature. Most children with short stature will have constitutional delay of growth and puberty (CDGP) or familial short stature, or there will be no identifiable cause. [patient.info]
Common characteristics include distinctive facial features, short stature and skeletal abnormalities, and mild to moderate intellectual disability. [rch.org.au]

Jaw & Teeth
- Delayed Dentition
SHORT syndrome is a rare, multisystem disease characterized by short stature, anterior-chamber eye anomalies, characteristic facial features, lipodystrophy, hernias, hyperextensibility, and delayed dentition. [ncbi.nlm.nih.gov]
Delayed dentition, hypodontia, enamel hypoplasia, malocclusion and multiple dental caries are frequently reported. Ophthalmic anomalies (e.g. Rieger anomaly, Axenfeld anomaly (see these terms), glaucoma) are also characteristic of the disease. [orpha.net]
- Dental Caries
Delayed dentition, hypodontia, enamel hypoplasia, malocclusion and multiple dental caries are frequently reported. Ophthalmic anomalies (e.g. Rieger anomaly, Axenfeld anomaly (see these terms), glaucoma) are also characteristic of the disease. [orpha.net]
Thus, dental problems like overcrowded teeth (5/6), hypodontia, and dental caries in SHORT syndrome patients warrant a closer look and early identification before they progress further down the road. [bmcmedgenet.biomedcentral.com]
Dental problems consist of delayed secondary tooth eruption, small or absent teeth, malposition, malocclusion, overcrowding of teeth, dental caries on the perilingual maxillary surface (due to gastro-oesophageal reflux disease (GERD)), periodontal disease [nature.com]

Eyes
- Visual Impairment
Such eye abnormalities may result in varying degrees of visual impairment. In cases of blepharospasm, an inability to open the eyelids due to involuntary muscle spasms may result in functional blindness. [rarediseases.org]
The primary characteristics are: -Visual impairment caused by retinal abnormalities -Obesity, typically apparent by age one -Polydactyly (extra fingers or toes) -Hypogonadism -Renal anomalies (kidney malformations and/or malfunctions) -Learning disabilities [bardetbiedl.org]
Children with Down syndrome are at increased risk for visual impairment. Common visual problems include crossed eyes, near- or farsightedness, and cataracts. Most visual problems can be improved with glasses, surgery, or other treatments. [stanfordchildrens.org]
Visual and hearing impairments in addition to intellectual disability may further limit the child’s overall function and may prevent him or her from participating in important learning processes and developing appropriate language and interpersonal skills [emedicine.medscape.com]
Visual impairments occur in 44–53% of individuals with NIPBL, SMC1A and HDAC8 variants 3, 41 and those without detectable disease-causing variants 98. [nature.com]

- Neurologic Manifestation
Specifically, IVIG plus corticosteroids group patients had higher frequency of respiratory, ocular, and cardiovascular involvement compared with the corticosteroids group and more neurologic manifestations compared with the IVIG group. [jamanetwork.com]
MRI findings usually do not contribute to regular clinical care and should be limited to individuals with CdLS with neurological manifestations (R48). [nature.com]
Workup
Given the rarity of the condition (only 20 cases described until the end of the 20th century), the diagnosis of SHORT syndrome is difficult. But because clinical suspicion can only be raised after a thorough physical examination and a properly obtained patient history, these two steps must be regarded as essential in order to make the diagnosis. Identification of the five cardinal features that constitute the SHORT acronym will almost undoubtedly confirm the diagnosis. On the other hand, several reports imply that an autosomal dominant pattern of inheritance is the mode of SHORT syndrome transmission, although many cases have developed following de novo mutations without any association suggesting a familial event [1] [2] [6]. Nevertheless, a comprehensive family history should be obtained. The cause of SHORT syndrome was unknown until recently, but the discovery of phosphatidylinositol 3 kinase (PI3K) mutations in practically all individuals has opened up the possibility of genetic testing in patients with the typical clinical features of SHORT [1] [3] [5]. These tests are scarcely available, however, which is why the diagnosis rests on clinical criteria. Mutations in BMP4 and the PITX family of genes have also been described in certain studies, but their roles are yet to be confirmed [5] [6].
