Anticipation (genetics)
From Biocrawler, the free encyclopedia.
In medicine, anticipation is the severity of a genetic disorder increasing with each generation. Measurement of anticipation is based on the age of the patient when they first displayed symptoms of the disease and comparing this to historical data about the average age of onset in past generations. It occurs in a number of diseases, including Huntington's disease, myotonic dystrophy and fragile X syndrome.
