How is SHOX-related short stature inherited?

SHOX-related short stature follows an X-linked inheritance pattern. Because the gene is located on the X chromosome, the condition may affect males and females differently.

How rare is SHOX-related short stature?

SHOX-related short stature is classified as not well established. The estimated prevalence is approximately Unknown. Because rare disease data can be limited, actual numbers may differ from published estimates.

How is SHOX-related short stature diagnosed?

Diagnosis is based on clinical findings including measurements of height, assessment of bone age, and evaluation of limb proportions. Radiological signs that resemble those seen in Leri-Weill dyschondrosteosis help support the diagnosis. Other tests, such as checking hormone levels and karyotype, may be performed to rule out other causes of short stature.

Are there treatments for SHOX-related short stature?

Information about treatment is currently limited for this condition.

What complications might arise from SHOX-related short stature?

People with SHOX-related short stature may experience additional skeletal changes as they grow older. While some individuals may not develop further complications, others might see changes like mesomelic disproportions or Madelung deformity later in life. It's important to monitor growth and any changes in bone structure over time.

How does SHOX-related short stature affect daily life?

SHOX-related short stature can impact daily life, especially in activities that require height or reach. Children may face challenges in physical activities or social situations due to their shorter stature. However, with support and understanding from family and friends, they can lead fulfilling lives and participate in various activities.

What is the long-term outlook for someone with SHOX-related short stature?

The long-term outlook for individuals with SHOX-related short stature can vary. While the condition primarily affects height, many people do not experience serious health problems. Some may have additional skeletal changes later in life, but overall, most individuals can expect to lead healthy lives.

Should families consider genetic counseling for SHOX-related short stature?

Yes, families may want to consider genetic counseling for SHOX-related short stature. Since the condition is inherited in an X-linked pattern, understanding the risks for future children can be helpful. A genetic counselor can provide information about inheritance patterns and help families make informed decisions.

Rare Disease

SHOX-related short stature

MONDO:0010367

Also known as:short stature, idiopathic familialISSshort stature, idiopathic, X-linked

Overview

SHOX-related short stature is a primary bone dysplasia characterized by a height that is 2 standard deviations below the corresponding mean height for a given age, sex and population group, in the absence of obvious skeletal abnormalities and other diseases and with normal developmental milestones. Patients present normal bone age with normal limbs, shortening of the extremities (significantly lower extremities-trunk and sitting height-to-height ratios), normal hGH values, normal karyotype, and Leri-Weill dyschondrosteosis-like radiological signs (e.g. triangularization of distal radial epiphyses, pyramidalization of distal carpal row, and lucency of the distal radius on the ulnar side). Mesomelic disproportions and Madelung deformity are not apparent at a young age, but may develop later in life or never.

Clinical Presentation

Built from Human Phenotype Ontology (HPO) phenotype annotations and GeneReviews clinical descriptions. Features represent findings documented across known cases — not an exhaustive list of possible symptoms.

Features include: Short stature.

Genetic Landscape

Assembled from HGNC gene records, ClinGen gene-disease validity evidence, and ClinVar pathogenic variant data. Validity classifications reflect the strength of published evidence linking each gene to this disease.

SHOX function has not been fully characterized.

SHOX-related short stature is associated with mutations in the SHOX gene on chromosome X.

GeneReviews

Clinical Guidance

No correlation has been established between the severity of phenotype and the underlying SHOX pathogenic variant [, , , ]. Based on a limited number of studies, the frequency of LWS is greater than SHOX-deficient short stature caused by a SHOX enhancer deletion , suggesting that enhancer deletions cause a more severe phenotype. In the French population, however, deletions of the downstream enhancer region of SHOX appear to be associated with a milder phenotype . Thus, this issue remains unresolved.

Diagnosis

Drawn from GeneReviews diagnostic guidelines, newborn screening panel status (RUSP), and ClinGen gene-disease validity classifications. Reflects current clinical evidence and consensus where available.

GeneReviews

Diagnostic Criteria

The phenotypic spectrum of SHOX deficiency disorders, caused by haploinsufficiency of the short stature homeobox-containing gene (SHOX), ranges from nonspecific short stature with absence of mesomelia and Madelung deformity (called SHOX-deficient short stature in this GeneReview) at the mild end of the spectrum to Leri-Weill dyschondrosteosis (LWD) at the severe end of the spectrum.

Suggestive Findings

SHOX-related Leri-Weill dyschondrosteosis (LWD) should be suspected in individuals with the following clinical and radiographic findings.

Clinical Findings of LWD

Treatment

Compiled from FDA-approved drug records, orphan drug designations, and FDA Adverse Event Reporting System (FAERS) safety data. GeneReviews management guidance is included where available.

No approved treatments are currently available for SHOX-related short stature. The disease remains an area of unmet medical need.

Management Guidelines

Evaluations Following Initial Diagnosis

To establish the extent of disease and needs in an individual diagnosed with SHOX deficiency, the evaluations summarized in this section (if not performed as part of the evaluation that led to the diagnosis) are recommended :

Prognosis

Based on GeneReviews surveillance recommendations, HPO phenotype frequency and severity annotations, and published prevalence estimates from Orphanet and OMIM.

GeneReviews

Surveillance Guidelines

The growth of a child with SHOX deficiency should be monitored every six months. In case of growth failure or short stature, treatment with recombinant human growth hormone is an option to increase growth rate and adult height; consultation with a pediatric endocrinologist is recommended.

Frequently Asked Questions

Common questions about SHOX-related short stature

SHOX-related short stature is a type of primary bone dysplasia where people have a height that is significantly below the average for their age, sex, and population group. The condition is noted when there are no obvious skeletal abnormalities or other diseases that explain the short stature. People with this condition show a normal bone age and normal limb appearance along with characteristic radiological signs. These can include features like the triangular shape of the distal radial epiphyses and pyramidal arrangement of the distal carpal row. This description helps distinguish the condition from other causes of short stature.

Common signs include a height that is 2 standard deviations below the average along with shortening of the extremities. Radiological findings such as triangularization of the distal radial epiphyses, pyramidalization of the distal carpal row, and lucency on the ulnar side of the distal radius can be seen. Other typical features such as mesomelic disproportions or Madelung deformity may not be present early in life, but could develop later or may not appear at all.

This condition is caused by changes in the SHOX gene. It is inherited in an X-linked pattern, which means the gene change can affect people in a family across different generations. The presence of a normal karyotype and normal hGH values helps to rule out other conditions. Associated genes include SHOX.
