Not exact matches

The researchers determined that CRISPR had successfully corrected a gene that causes blindness, but Kellie Schaefer, a PhD student in the lab of Vinit Mahajan, MD, PhD, associate professor of ophthalmology at Stanford University, and co-author of the study, found that the genomes of two independent gene therapy recipients had sustained more than 1,500 single - nucleotide mutations and more than 100 larger deletions and insertions.

The findings jibe with previous reports that PCR tests sometimes overlook a gene with large deletions, detecting only the other, normal copy of the gene.

The result was the largest deletion ever observed in the dystrophin gene using CRISPR / Cas9, and the study was the first to create corrected human iPS cells that could directly restore functional muscle tissue affected by Duchenne.

A change in every 100th base could affect thousands of genes, and the percentage difference becomes much larger if you count insertions and deletions.

Researchers checked the genomes of 150 patients with schizophrenia and those of 268 healthy people, looking for large duplications and deletions of genetic material that disrupted the function of a gene.

A very rare form of a thalassemia is due to a deletion of a larger area of chromosome 16 including the a globin genes.

Indeed, re-analysis of the results show that large genes host 51 % of recurrent cancer deletions, and that many of these genes are associated with CFSs in at least one of the cell types in which we mapped them.

Large - scale targeted - deletions have been successful in defining gene functions in the single - celled yeast Saccharomyces cerevisiae, but comparable analyses have yet to be performed in an animal.

They also described the gene's size and genetic deletions associated with disease, including a very large deletion of the gene coding for dystrophin found in a patient with mild disease.

Any large deletions, or other rearrangements of part of a chromosome can be identified, and using modern nucleic acid probes, individual cloned genes can be placed on the polytene map.

A large genomic deletion that removes all exons of CNGB3, the gene that encodes the β subunit of the cone cyclic nucleotide-gated cation channel, has been identified in CD - affected Alaskan Malamute - derived dogs, although there is evidence that the condition might be genetically heterogeneous in this breed as some dogs have been identified with clinical signs of day blindness that lack the CNGB3 deletion [68].

CEA, which segregates in several herding breeds with Collie ancestry, was mapped to a large region of CFA37 that included over 40 genes [92]; subsequently the fact that the disorder segregates in multiple, closely related breeds was used to reduce the size of the critical disease - associated region and pinpoint the causal mutation to a 7.8 kb intronic deletion in the NHEJ1 gene, which spans a highly conserved binding domain to which several developmentally important genes bind [91].
