CONCLUSIONS: These results suggest that the behavioral expression of
allelic variation in MAOA activity is sensitive to social experiences early in development and that its functional outcome might depend on social context.
Allelic variation in this transporter's gene expression, regulated by a 43 bp indel in the upstream region termed 5 - HTTLPR, was initially associated with anxiety - related traits (23) and has since been investigated in many fields of serotonin - related human genetics (24).
We examined the influence of a common
allelic variation in the dopamine receptor D4 (DRD4) gene and caregiver quality on temperament in early childhood.
Socio - economic status covaries with central nervous system serotonergic responsivity as a function of
allelic variation in the serotonin transporter gene - linked polymorphic region
Examples include the study of
allelic variation in the human genome and the development of computational methods for the discovery of cancer - associated genes and diagnostic cancer markers using genomic profiles derived from different tumor types.

The
variation in the ethnic composition of the urban and rural populations of the Brazilian Amazon region and of distinct regions
in Brazil [26, 46], may influence the
allelic and genotypic distributions reflecting
in matrixes of genetic mechanisms favorable to the susceptibility to infectious and parasitic diseases,
in particular to malaria.
In humans, disease susceptibility was mapped to a non-coding 6.1 kb 3» region of CTLA4, the common
allelic variation of which was correlated with lower messenger RNA levels of the soluble alternative splice form of CTLA4.
BACKGROUND:
Allelic variation of the monoamine oxidase A (MAOA) gene has been implicated
in conduct disorder and antisocial, aggressive behavior
in humans when associated with early adverse experiences.
