Although knowledge of the immunology of pregnancy has evolved tremendously over the past decade, many unanswered questions remain, such as how immune function is altered during pregnancy and how this alteration may affect susceptibility to and severity of infectious diseases.
Furthermore, since the K145N substitution is located within a glycosylation site, the charge alteration may affect glycosyl transferase activity, which results in altered glycosylation.
Anthropogenic habitat alteration may affect the dispersal service provided by avian seed dispersers, ultimately causing regeneration collapse, through a decay in both the quantitative (seed removal) and qualitative (seed arrival to safe sites) components of seed dispersal effectiveness.
Metabotropic glutamate receptor-1 (GRM1) has been reported as an oncogene in the progression of triple negative breast cancer [ 61], whose alteration may affect the pathway Alanine, aspartate and glutamate metabolism.

In the semi-intensive and intensive culture, these alterations may affect the natural resistance of fish against parasites.
These alterations may affect only one or both hemi-diaphragms and may present with different intensities, ranging from only a partial loss of the ability to generate negative pressures (weakness) to a complete loss of diaphragmatic function (paralysis) [5].
Our analyses demonstrate that genomic alterations may affect multiple pathways, which could be classified as drug effector and non-effector pathways by the way they target the two cancer hallmarks 'sustaining proliferative signaling' and 'evading growth suppressors' [21].
These alterations may affect memorization and emotional behavior [ 99].
In silico analysis suggests that these sequence alterations may affect splicing and protein conformations [ 41].
