Donor Information#

General Donor Information

Sex female

Phenotype and Disease related information (Donor)

Diseases A disease was diagnosed.
Parkinson 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
The donor is a carrier of a disease-associated mutation and affected.
Genetic variants
SNCA (target)
4q22.1
Heterozygous
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
Is the medical history available upon request? Y Mov Disord. 2011 Sep;26(11):2134-6. doi: 10.1002/mds.23776

Genetic modifications
SNCA (target)
Gene knock-out
4q22.1
The SNCA 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 SNCA. 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.
