Mouse Stard8 Knockout Project (CRISPR/Cas9)
Objective: To create a Stard8 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering.
Strategy summary: The Stard8 gene (NCBI Reference Sequence: NM_199018 ; Ensembl: ENSMUSG00000031216 ) is located on Mouse chromosome X. 14 exons are identified, with the ATG start codon in exon 4 and the TGA stop codon in exon 14 (Transcript: ENSMUST00000036606). Exon 4~14 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:
Exon 4 starts from about 0.03% of the coding region. Exon 4~14 covers 100.0% of the coding region. The size of effective KO region: ~8797 bp. The KO region does not have any other known gene.

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.
