RhAPPcast: Unpacking the Genetics: Low ALP

In this episode of RhAPPcast, the official podcast of Rheumatology Advanced Practice Providers, host Amanda Mixon sits down with rheumatology PA Heather Mambretti to explore the clinical significance of low alkaline phosphatase (ALP) and why this often overlooked lab value may signal important genetic conditions such as hypophosphatasia (HPP). The conversation highlights how persistently low ALP can be a key clue in patients presenting with vague musculoskeletal symptoms, unexplained fractures, dental abnormalities, or chronic fatigue—symptoms frequently encountered in rheumatology clinics. Heather explains how clinicians should approach the diagnostic workup, including trending ALP levels over time, reviewing dental and family history, evaluating radiographic findings, and considering ALPL gene testing when hypophosphatasia is suspected.

The episode also provides practical guidance for rheumatology clinicians and advanced practice providers on integrating low ALP awareness into routine clinical assessments, avoiding missed diagnoses, and recognizing that adult hypophosphatasia may be more common than previously thought. Listeners will learn how identifying genetic causes of low ALP can improve patient outcomes, guide appropriate management, and even help uncover undiagnosed cases within families. This discussion offers valuable insights for rheumatology providers involved in bone health, osteoporosis evaluation, and the investigation of unexplained musculoskeletal complaints.
