Gene/Transgene symbol	Nfix

Information from provider

Provider	Raj Thakker
Provider affiliation	Academic Endocrine Unit, University of Oxford
Genetic information	CRISPR/Cas9-generated mutation which has induced a 140bp deletion in exon 7 of the Nfix (Chr 8) gene, encompassing critical exon, to induce a premature stop codon and a null allele. More specifically, Nfix Del140 contains a 140-nucleotide deletion (from position +49,577 to +49,716 relative to the translational start site) and comprised 53 nucleotides from exon 7 and 87 nucleotides of intron 7.
Phenotypic information	Homozygous: Homozygous mice are viable, normal, and fertile, with no skeletal abnormalities. Heterozygous: Heterozygous mice are viable, normal, and fertile, with no skeletal abnormalities.
Breeding history	Coisogenic on C57BL/6J background.
