A frameshift mutation is a type of gene mutation wherein the addition or deletion of (a number of) nucleotide(s) causes a shift in the reading frame of the codons in the mRNA. This leads to the alteration in the sequence of amino acids during protein translation. ...
2018 European Cystic Fibrosis Society Background: The Q359K/T360K mutation, described in Jewish CF patients of Georgian decent, is of questionable clinical significance. Methods: Clinical records of patients with the Q359K/T360K mutation from three CF centers were studied for phenotypic expression ...

This is a report of the results of a worldwide survey of the most common mutation (deltaF508) that causes cystic fibrosis (CF). The data are listed according to geographical location (in alphabetic order), beginning with the group with the largest number of CF chromosomes. Data consisting ...
No deltas need apply: Will DNA mutation deltaF508 make you an outcast?Says that the ability to screen for the mutation deltaF508 that causes cystic fibrosis is not only an early example of the type of genetic testing that will be increasingly available but is a knowledge that has impact ...
This mutation, among others, leads to a class II mutation of cystic fibrosis. The misfolded CFTR is either not transported to the surface of the membrane or is only transported in residual amounts, preventing the regulation of mucus consistency and causes cystic fibrosis. The mechanism of the ...
DNA Replication and Causes of Mutation This article describes the DNA repair mechanisms used in the cell and how mutations occur. LA Pray - 《Nature Education》 被引量: 46发表: 2008年 Mutation and the replication of DNA. By the use of chloramphenicol and a thymine-less mutant of E. coli,...
(germinal mutations) may result in an individual offspring all of whose cells carry the mutation, which often confers some serious malfunction, as in the case of ahuman genetic diseasesuch ascystic fibrosis. Mutations result either from accidents during the normal chemical transactions of DNA, ...
Many genetic mutations are expressed as morphological abnormalities. These mutations can be of dominant or recessive genes of either the autosomes or the sex chromosomes. For some of these conditions (e.g.,hemophilia, Lesch-Nyhan syndrome,muscular dystrophy, cystic fibrosis), the molecular or biochem...
to responses to aberrant gene expression processes like the accumulation of unfolded or unstable CFTR protein or the activation of RNA degradation pathways, i.e., to the specific mechanisms through which each mutation causes disease (absence of protein, impaired trafficking, defective gating, etc.)....
