ICD-10: G71.038

Limb-girdle muscular dystrophies (LGMD) represent a diverse group of genetic disorders characterized by progressive weakness and wasting of the proximal muscles, particularly those around the hips and shoulders. The ICD-10 code G71.038 specifically refers to "Other limb girdle muscular dystrophy," which encompasses various subtypes that do not fall under the more commonly recognized categories of LGMD. Below is a detailed overview of the clinical presentation, signs, symptoms, and patient characteristics associated with this condition.

Clinical Presentation

Signs and Symptoms

The clinical presentation of LGMD, including those classified under G71.038, can vary significantly depending on the specific subtype and the age of onset. Common signs and symptoms include:

• Muscle Weakness: The hallmark of LGMD is progressive muscle weakness, particularly affecting the proximal muscles of the pelvis and shoulder girdles. Patients may experience difficulty with activities such as climbing stairs, lifting objects, or raising their arms[1].

• Muscle Wasting: Over time, affected muscles may show signs of atrophy, leading to a noticeable decrease in muscle mass[1].

• Gait Abnormalities: Patients often develop a waddling gait due to weakness in the hip muscles, which can lead to balance issues and an increased risk of falls[1].

• Joint Contractures: Some individuals may develop contractures, which are permanent tightening of muscles or tendons that restrict movement around joints[1].

• Cardiac and Respiratory Involvement: In certain subtypes, there may be associated cardiac or respiratory muscle involvement, leading to complications such as cardiomyopathy or respiratory failure[1].

Age of Onset

The age of onset for LGMD can vary widely. Some individuals may present symptoms in childhood, while others may not show signs until adulthood. Early-onset forms tend to be more severe, whereas late-onset forms may progress more slowly[1].

Patient Characteristics

Genetic Background

LGMD is genetically heterogeneous, with various mutations leading to different subtypes. The specific genetic mutation can influence the severity and progression of the disease. Genetic testing is often recommended to identify the underlying cause, which can aid in prognosis and management[2].

Family History

A family history of muscular dystrophy or related conditions is common among patients with LGMD. This genetic component underscores the importance of genetic counseling for affected individuals and their families[2].
