CF gene may protect against typhoid fever

  title={CF gene may protect against typhoid fever},
  author={D. Josefson},
The gene mutation that causes cystic fibrosis may confer resistance to typhoid fever and to several other infectious agents. The finding may explain why the cystic fibrosis mutation is so prevalent. Cystic fibrosis develops in children who inherit two mutant copies of the gene that encodes a protein known as cystic fibrosis transmembrane conductance regulator (CFTR). Abnormal CFTR …

Why Recessive Lethal Alleles Have Not Disappeared?
It is shown that recessive advantage of a lethal gene can be detected by the ratio of heterozygotes and homozygotes, and demonstrates that higher IQ of certain ethnic groups cannot be explained by recessives advantage of lethal genes. Expand
Mistargeting of a truncated Na-K-2Cl cotransporter in epithelial cells.
A mouse model using CRISPR/cas9 that reproduces the 11 bp deletion in exon 22 of Slc12a2 is created that shows that the colon and salivary gland expresses wild-type NKCC1 abundantly at the apical pole, confirming the data obtained in cultured epithelial cells. Expand
A new test suggests that balancing selection maintains hundreds of non-synonymous polymorphisms in the human genome
A new test, based on the McDonald-Kreitman test, is introduced, in which the number of polymorphisms that are shared between populations is contrasted to those that are private at selected and neutral sites, which concludes that more than a thousand non-synonymous polymorphisms are subject to balancing selection.

A bridge between neuroscience and oncology: prostate cancer genesis. A 'negative' consequence of learning?
The observation, that the cancer incidence in patients with chronic neurological disabilities is significantly lower than in the normal population lead to the hypothesis, that changed processing due to a barrage of aberrant sensory information within a healthy CNS can trigger events within the prostate cell, that cause malignant transformation.
