A TI{CRIMIC.TG4.2} DNA cassette has been inserted into snama, in a coding intron, and is predicted to gene trap a subset of the annotated transcripts of the gene (insertion is in a coding intron of snama-RA and in an exon in the 3' UTR of snama-RB). 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: TCGAGGCCACTGGAACTCCGAGG.
