Endocrine Conditions
- Precocious Puberty
- Hypothyroidism
- Short Stature
- Adrenal Insufficiency
- Failure to Thrive/Poor Weight Gain
- Obesity has only been reported by individuals with an 8p deletion only
While the exact prevalence and impact are still being studied, providers should be aware of these potential health concerns and manage them according to standard clinical practice.
Short Stature
If a child is shorter than their peers but growing at a consistent rate, this may not warrant concern. However, a noticeable decrease in growth rate over the course of a year may require further medical evaluation to identify potential underlying factors.
Typical growth patterns include:
- Approximately 10 inches during the first year of life
- Approximately 5 inches between ages 1 and 2
- Approximately 3.5 inches between ages 2 and 3
- Approximately 2 inches per year from age 3 until puberty1
16% of 8p Heroes in the Chromosome 8p report short stature

While the exact prevalence of Short Stature in individuals with chromosome 8p rearrangements is not well established, it is recognized as a common symptom. Research provides a clearer picture of the prevalence range, although results can vary based on the size and characteristics of the populations studied.
- A 2019 study, Clinical and genomic characterization of 8p cytogenomic disorder reported 14% of the participating patients had Short Stature.2
Screening
- Height (length for those who cannot stand), weight and BMI should be taken at every visit.
- A noticeable plateau or halt in growth compared to prior percentiles should lead to further evaluation, such as investigating nutritional deficiencies or potential endocrine issues.
Treatment
- The treatment for short stature depends on the underlying cause, as well as the child’s age, overall health, and medical history. In many cases, close monitoring of the child’s growth and development is all that is required.
- If malnutrition is identified, nutritional therapy should be initiated to support growth.
- If a hormone imbalance is suspected, consultation with an endocrinologist is recommended for further evaluation and management.

This visualization is powered by research sponsored by Project 8p and survey data collected from the Chromosome 8p Registry, representing insights from a total of 120 8p heroes. It is part of the soon-to-launch Insights Portal, designed to offer advanced tools for data analysis, access, and visualizations, accelerating research and discovery for chromosome 8p disorders.
