Acid-labile subunit deficiency
Overview
Acid-labile subunit deficiency is a rare genetic condition that affects the body's ability to make enough of a protein called acid-labile subunit (ALS). This protein plays a key role in helping regulate the levels of certain hormones in the body, including insulin-like growth factor-1 (IGF-1). Without enough ALS, the body may not be able to produce and use IGF-1 properly, which can lead to a variety of health problems.
People with acid-labile subunit deficiency may experience stunted growth and development, as IGF-1 is important for normal growth during childhood and adolescence. They may also have low levels of glucose in their blood, as IGF-1 helps regulate the body's response to insulin. Additionally, individuals with this condition may have delayed puberty, reduced muscle mass, and increased fat accumulation. Acid-labile subunit deficiency is typically diagnosed through genetic testing and treatment may involve hormone replacement therapy to help manage the symptoms associated with the condition.
