Due to a mutation that changes a coding codon into a termination codon, such a mutation is known as Huntington gene's first exon shows (CAG)n repeats, with less than 35 repeats considered normal and more than 35 leading to Huntington disease. This mechanism of disease caused by the change in (CAG)n repeat number is known as Which mechanism generally causes only a change in gene expression levels?
