E34.328
Other genetic causes of short stature
Clinical Classification Guidelines
Inclusion Terms
- Short stature due to ACAN gene variant
- Short stature due to aggrecan deficiency
- Short stature due to NPR-2 gene variant
Medical Intelligence & Overview
ICD-10 code E34.328 refers to various genetic factors that can lead to short stature, a condition where an individual’s height is significantly below the average for their age and sex. This code includes conditions caused by gene variations affecting growth, such as mutations in the ACAN, NPR-2, and other related genes. Understanding these genetic causes can help in the diagnosis and management of growth-related issues, though it's important to consult with healthcare professionals for personalized advice.
Causes & Symptoms
Clinical Causes: Genetic mutations in the ACAN gene, which encodes aggrecan, a critical component of cartilage involved in bone growth. Variants in the NPR-2 gene, which plays a role in bone growth regulation through its influence on growth plates. Other rare genetic mutations that impair normal growth development and result in short stature.
Key Symptoms: Consistently short height compared to peers of the same age and sex. Normal development of other physical features and intelligence, with the primary concern being stature. Possibility of disproportionate body parts, depending on the specific genetic mutation. Potential delayed puberty or other hormonally related growth issues, depending on the underlying cause.
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a comprehensive medical history, physical examination, and genetic testing. Blood tests may also be performed to rule out other causes of short stature. Identifying specific gene mutations, such as those in ACAN or NPR-2, confirms the genetic basis for the condition. Imaging studies like X-rays can assess bone age and growth plate development to support diagnosis.
Treatment Protocols: While some genetic causes of short stature may not have a direct cure, management strategies aim to optimize growth and overall health. These include:
