To estimate: The age at which half of individuals carrying a Huntington’s disease allele will develop symptoms. Introduction: Huntington’s disease (HD) is a genetic disorder which causes progressive degeneration of nerve cells in the brain. It impairs the cognitive and functional abilities of a person. HD occurs due to an increase in the CAG trinucleotide repeats in the HD gene. It follows autosomal dominant inheritance pattern. An affected individual inherits the mutated gene from one of the affected parents. Every child with an affected parent has 50% chance of getting HD. The usual age of onset is 30-50 years.
