A TI{CRIMIC.TG4.2} DNA cassette has been inserted into ifc, in a coding intron, and is predicted to gene trap a subset of the annotated transcripts of the gene; the insertion is in the coding intron of 1 annotated transcript and in a non-coding exon of 1 transcript. The TI{CRIMIC.TG4.2} cassette was inserted via the CRISPR/Cas-9 drop-in technique, using a dsDNA donor vector with homology arms of length 200bp. The sgRNA sequence used to target the gene was: TTAATTGCGCCGATTAGATAAGG.
