Abstract

Family mapping is a useful tool for tracking the inheritance of rare inherited diseases, including hypophosphatasia (HPP), through generations. We show the inheritance of HPP in 6 affected families, describing genetic variants, biochemical hallmarks, and clinical manifestations among family members. Mapping families with HPP is warranted in clinical practice to better understand monitoring needs for potentially affected individuals over time, since manifestations of HPP can arise throughout a patient's lifespan.
