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.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
