Instability of cgg repeats in transgenic mice
NettetIt arises due to expansion of a CGG repeat which is present in the 5′-untranslated region of the FMR1 gene, disruption of which leads to mental retardation. The mechanisms involved in trinucleotide repeat expansion are poorly understood and to date, transgenic mouse models containing transgenic expanded CGG repeats have failed to reproduce the … Nettet1. mar. 1996 · While in mammals some evidence suggests that short inverted repeats (<10 bp long) may show instability, nothing is known about the stability of long …
