De novo exon duplication in a new allele of mouse Glra1 (spasmodic)

Genetics. 2006 Dec;174(4):2245-7. doi: 10.1534/genetics.106.065532. Epub 2006 Oct 8.

Abstract

The novel neurological mutant Cincinatti arose by genomic duplication of exon 5 in the glycine receptor gene Glra1. The mutant transcript results in premature protein truncation. A direct repeat of the pentamer GGGGC is present adjacent to the breakpoints and may have mediated the duplication event by a replication slippage mechanism.
