What is Huntington disease?

Description:
People with Huntington disease (HD) have an extended version of this HD or huntingtin gene. The extension is caused by a repeated region consisting of three bases: C-A-G. The larger gene produces a protein that accumulates over time and begins to kill brain cells when the person reaches middle age.

The protein encoded by the FGFR3 gene usually receives and transmits signals that stimulate cell maturation. Mutations in this gene cause a dysfunctional protein to be produced that causes a disruption to growth, known as achondroplasia or dwarfism.
