The SHOX Gene The SHOX gene is present on both the X and Y sex chromosomes, in a location called the pseudoautosomal region. This region is so-called because it is comprised of homologous sequences which are present on both sex chromosomes. [brighthub.com]

- Malnutrition
Hormone disorders, malnutrition, chronic disease, or a genetic disorder are some of the causes of short stature. [timesofindia.indiatimes.com]
Worldwide, malnutrition is the most common cause of growth failure and is usually related to poverty or anarchy. Nutritional deficiencies in developed countries are more often the result of self-restricted diets. [emedicinehealth.com]

Growth failure associated with CRI usually begins when the glomerular filtration rate falls to 50% of normal. [nice.org.uk]
Short Stature in Children Causes All causes of short stature fall into one of three major categories: chronic disease (for example, malnutrition), familial short stature, or constitutional delay of growth and development ("late bloomers"). [emedicinehealth.com]

- High Arched Palate
Physical examination was remarkable for high arched palate, mild thyromegaly, grade I/VI systolic ejection murmur over right upper sternal border, multiple nevi, breasts Tanner stage II, and pubic hair Tanner stage IV. Bone age was 15 years. [cmecorner.com]
The loss of the SHOX gene therefore leads to short stature and various skeletal abnormalities, such as short metacarpals, high-arched palate, cubitus valgus, Madelung deformity, and mesomelia. [naturalheightgrowth.com]
They are shortening of the fourth and fifth metacarpals, high arched palate, increased carrying angle of the elbow, scoliosis, and micrognathia [ 35 ]. [karger.com]

Treatment
Treatment for restricted growth Treatment with growth hormone injections may benefit some people with restricted growth and can help a child with the condition grow more than they otherwise would. [nhsdirect.wales.nhs.uk]
Medical Treatment Medical Treatment Medical treatment depends on the cause of short stature. For children with normal variant short stature, generally no treatment is necessary. [emedicinehealth.com]
Children may be referred and evaluated too late to receive effective treatment for their condition. Early diagnosis and treatment can improve the clinical outcomes of disease. [cmecorner.com]
Protocol Description The main objective of this multicenter international study is the collection and analysis of data regarding safety and effectiveness of Humatrope® for the treatment of growth-hormone deficiency and other growth disorders. [chp.edu]
Chondrodystrophies Most chondrodystrophies have no specific treatment, although GH is FDA-approved for treatment of SHOX deficiency (see previous paragraph on SHOX deficiency). [endocrinologyadvisor.com]
