Sentences with phrase «frameshift mutation»
A "frameshift mutation" is a type of genetic change that occurs when the letters of DNA are added or removed, changing the reading frame. This causes a disruption in the instructions for building proteins, leading to faulty or non-functional proteins being made. Full definition
DMD is caused primarily by frameshift mutations in dystrophin, a protein essential for proper muscle function.

Surprisingly, frameshift mutations occurred at a ratio of 0.90 in - frame per out - of - frame mutation as opposed to the expected frequency of 0.50 (1 in - frame per 2 out - of - frame mutations; Table S1).
However, while CRISPR is remarkably effective for introducing non-sequence specific frameshift mutations through aberrant double strand break repair, it has proven more challenging to develop high efficiency CRISPR - based approaches for the generation of knockins via homologous recombination with a homologous repair template.
DVL1 frameshift mutations clustering in the penultimate exon cause autosomal - dominant Robinow syndrome.
MSTN expression was not observed in cloned goats (Figure 3D), which confirmed disruption of MSTN expression resulting from frameshift mutations.
We imputed these variants into 104,220 individuals down to a minor allele frequency of 0.1 % and found a recessive frameshift mutation in MYL4 that causes early - onset atrial fibrillation, several mutations in ABCB4 that increase risk of liver diseases and an intronic variant in GNAS associating with increased thyroid - stimulating hormone levels when maternally inherited.
Red slashes indicate frameshift mutation eliminating UNC - 7L expression.
A CNGB1 frameshift mutation in Papillon and Phalène dogs with progressive retinal atrophy.
The four unrelated patients in the Bainbridge study had de novo nonsense and frameshift mutations in ASXL3 (not ASXL1).
Frameshift mutations is but one of the way of how information is added to genetic code through natural selection.
For example, we often screen only 15 - 25 mice when generating knockout models with CRISPR and find that many, if not all, the mice carry a frameshift mutation.
They identified five missense, one non-sense, three frameshift mutations and two large deletions involving several genes including RUNX1.
Programmable nucleases, ZFN, TALEN and RGENs enable gene knockout in cultured cells and organisms by producing site - specific DNA double - strand breaks, whose repair via error - prone non-homologous end joining (NHEJ) or microhomology - mediated end joining (MMEJ) gives rise to frameshift mutations.
They identified 3 homozygous variants in ATP6V1B: a frameshift mutation (p.Ile386Hisfs * 56), a nucleotide substitution in exon 10 (p.Pro346Arg), and a new splicing mutation in intron 5 and, 2 variants in ATP6V0A4: a homozygous variant (p.Arg743Trp) and a known missense mutations (p.Asp411Tyr).
Recently a frameshift mutation was identified in C2orf71 that causes an autosomal recessive form of late onset PRA in the Gordon and Irish Setters [30].
Unlike the genetically distinct, relatively late onset XLPRA1 that is described below, the phenotype associated with the frameshift mutation in XLPRA2 is very severe and manifests during retinal development.
