i don't know of a disease that results from a lost chromosome. however, downs syndrome is a result of an extra chromosome.
Huntington's disease is caused by a trinucleotide repeat expansion in the gene coding for Huntingtin (Htt) and is one of several polyglutamine diseases. This expansion produces an altered form of the Htt protein, mutant Huntingtin (mHtt), which results in neuronal cell death in select areas of the brain. Huntington's disease is a terminal illness.
Huntington's disease's most obvious symptoms are abnormal body movements called chorea and a lack of coordination, but it also affects a number of mental abilities and some aspects of personality. These physical symptoms occur in a large range of ages, with a mean occurrence in a person's late forties/early fifties. If the age of onset is below 20 years then it is known as Juvenile HD. As there is currently no proven cure, symptoms are managed with various medications and care methods.
