EDi001-A-4 Gene-edited iPSC line

Donor information


Disease status


Disease: Parkinson's disease
This is a PD line, with the control being EDi002-A lines and CRISPR/Cas9-corrected EDi001-A-1, EDi001-A-2, EDi001-A-3 and EDi001-A-4
Affected: Yes
Disease variant
Gene: SNCA
Chromosome location: 4q22.1
Zygosity: Heterozygous
Description: The donor carries a triplication of the alpha-synuclein gene, resulting in 4 copies of SNCA. The copies of SNCA are situated in a heterozygous triplication configuration. See Figure 1 of Petrucci, 2015 for a graphic representation of the heterozygous triplication.
Family history:Strong family history of Parkinson’s disease due to autosomal dominant inheritance of SNCA triplication
Medical history:Y Mov Disord. 2011 Sep;26(11):2134-6. doi: 10.1002/mds.23776

Disease/phenotype related genetic modifications

Disease: Parkinson's disease
Type of modification: Gene knock-out
Gene: SNCA
Chromosome location: 4q22.1
Delivery method: CRISPR-associated (CRISPR/Cas) System
Description: The SCNA triplication has been gene edited to become *putatively* normal. CRISPR/Cas was employed to create a mutation in Exon2, disrupting the ATG start site and some sequence 5' to the coding start of SCNA. PCR amplicons of the CRISPR site were cloned using the TOPO cloning technique. Sequencing of 8 TOPO clones detected 2 deletions, both of which disrupt the first ATG start site. This indicates 2 alleles were putatively knocked out, and 2 alleles remain. Additional comment: there are two additional ATG sites located immediately downstream of the normal ATG start site, one of which is in-frame (9 bases) to the initial ATG. It is possible that inactivation of the first ATG start site might not be completely sufficient to prevent translation from the second downstream ATG, which is in-frame to the first.

Cell Line Information Pack
A Cell Line Information Pack (CLIP) is created to communicate cell line specific information relating to restrictions on use to a user accessing cell lines from EBiSC. A CLIP contains information about a cell line including any specific third party obligations (TPOs) relating to, for example, intellectual property (IP) or the donor consent which affect the use of the cell line.
