Genetic information | A Kidins220 cDNA encoding exon 16 and polyA cassette flanked by two loxP sites, was inserted in the unique NruI site within exon 16 of the mKidins220 gene. In Kidins220 lox/lox mice, Kidins220 mRNA is transcribed under the control of its endogenous promoter, generating the full-length protein (Cesca et al, Cell Death Diff, 2012). The floxed allele is hypomorph, likely because of the absence of the splicing cassette, which is located in the C-terminus-encoding part of the endogenous gene. |
Phenotypic information | Homozygous:When in homozygosis, males are not fertile, while lox/lox females breed normally. Homozygous lox/lox mice show a reduced expression of full length Kidins220 and a percentage of them develop ventriculomegaly, a neurodevelopmental abnormality often associated to intellectual disability (del Puerto et al, Mol Psychiatry 2021).Heterozygous:The mouse strain kept in heterozygosis is viable, with normal life span and normal breeding capabilities. |
Breeding history | Mice have been always bred on C57BL/6 background. |
