Mouse Fscn2 Knockout Project (CRISPR/Cas9)
Objective: To create a Fscn2 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Fscn2 gene (NCBI Reference Sequence: NM_172802 ; Ensembl: ENSMUSG00000025380 ) is located on Mouse chromosome 11. 5 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 5 (Transcript: ENSMUST00000026445). Exon 1~5 will be selected as target site. Cas9 and gRNA will be co-injected into fertilized eggs for KO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Mice homozygous for disruptions in this gene display retinal generation with structural abnormalities of the outer segment and depressed rod and cone ERGs that worsen with age.
Exon 1 starts from about 0.07% of the coding region. Exon 1~5 covers 100.0% of the coding region. The size of effective KO region: ~6398 bp. The KO region does not have any other known gene.

Overview of the Dot Plot (up) Window size: 15 bp
Forward Reverse Complement
Sequence 12
Note: The 2000 bp section upstream of start codon is aligned with itself to determine if there are tandem repeats. No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis.

Forward Reverse Complement
Sequence 12
Note: The 2000 bp section downstream of stop codon is aligned with itself to determine if there are tandem repeats. No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis.

Summary: Full Length(2000bp) | A(22.7% 454) | C(27.75% 555) | T(20.7% 414) | G(28.85% 577)
Note: The 2000 bp section upstream of start codon is analyzed to determine the GC content. No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.
