About This Genogram
A three-generation genogram illustrating the autosomal dominant inheritance pattern of Huntington's disease. The grandfather was diagnosed at 45 and died at 58. The father is showing early motor symptoms at 42. An aunt chose not to undergo predictive testing. The index patient, a 25-year-old, faces the difficult decision of whether to pursue genetic testing. CAG trinucleotide repeat counts and age of onset data are documented.
