Is huntington's disease a frameshift mutation
WebAfter the crossover, one of the chromosomes will have a Huntington allele with fewer CAGs than before. This is the “contracted allele ” due to the contraction of the number of CAGs. The other chromosome will have a Huntington allele with more CAGs than before. This expansion results in the “expanded allele .”.

WebJan 20, 2024 · HD is caused by a mutation in the gene for a protein called huntingtin. The defect causes the building blocks of DNA called cytosine, adenine, and guanine (CAG) to repeat many more times than they normally do. Most people have fewer than 27 CAG repeats in their HD gene, so they are not at risk for the disease.

WebJun 16, 2024 · A frameshift mutation is a type of gene mutation in which the addition or deletion of one or more nucleotides causes a shift in the reading frame of the codons in the mRNA, which may lead to the alteration in the amino acid sequence at protein translation. Variant: frame shift mutation. WebJan 13, 2024 · A genetic mutation is a permanent change to the nucleotide sequence of a gene. More often than not, such genetic mutations are advantageous – they enable evolution and produce new desirable traits in organisms. However, genetic mutations can also be problematic if they result in a disease.
