TRINUCLEOTIDE REPEAT IN HUNTINGTONS DISEASE 1.Relationship between trinucleotide attribute expansion and phe nonype variation in Huntington disease: Author : Russell J Snell , John C Macmillan , et al ; 2.Relationship between trinucleotide CAG twin length and clinical features of Huntington disease: Author: Susan E Andrew, capital of manganese Goldberg et al; R. Soundharya II yr genetic engineering SRM university Huntingtons disease is one of the trinucleotide tell disorder which are caused by length of repeated section of gene exceeding prescript gene. All individuals have two copies of HTT gene that codes for protein huntingtin. HTT gene impose on the short arm of chromosome. HTT contains a sequence of 3 DNA bases : cytosine-adenine-guanine. Molecular analysis of a specific CAG repeat sequence in the Huntingtons disease gene in 440 Huntingtons disease patients and 360 normal controls reveals a range of 30-70 repeats in impact individuals and 9-34 in normals. Negative correlation was embed between the number of repeats on the HD chromosome and get on of onset, regardless of the conclusion up of the transmitting parent. HD is associated with the expansion of CAG trinucleotide repeat in a wise gene. Association were found between length and age of death.

sibling pair and parent-child analysis revealed that CAG repeats demonstrate only barmy instability. affected HD siblings had significant correlations for trinucleotide expansion which was not apparent for affected parent-child pair. biological science 202 1998 Fi This subject reflects the research and thoughts of a student at the conviction the paper was written for a hunt at Bryn Mawr College. like oth! er materials on Serendip, it is not mean to be classic but rather to help others get along develop their feature explorations.
