In addition to large CNVs, genomes harbor a plethora of small insertions and deletions (indels) that contribute substantially to genome sequence divergence and that represent a major constituent of the known heritable human disease burden (Stenson et al. 2003).
Notably, DNA mismatch repair defects are a primary driver of mutational burden in heritable colorectal cancers.
The main motivation to screen brain images was to find some heritable measure of disease burden that might be closer to the underlying genetic effect than clinical diagnosis based on cognitive and clinical tests.
Epidemiological studies in Brazil have shown that the intensity of infection (worm burden) is a heritable phenotype (41%).
Conversely, risk stratification predicted by constitutional (heritable) genotypes is independent of leukaemia burden and offers scope for outcome prediction very early in treatment.
Such convergent findings should motivate studies that evaluate the cognitive, affective, and behavioral effects of bipolar genetic 'risk' variants in nonclinical populations, test for positive selection on such variants, and measure copy number burdens with regard to other heritable conditions involving exceptional human performance, such as high 'intelligence'intelligence
Our results suggest that heritable breast cancer represents a larger proportion of the total burden than conventionally thought.
For Ascaris a number of other parameters like actual worm burden, total egg output and antibody-levels were also heritable whereas this was not the case for the size and fecundity of the worms (Peter Nejsum, unpublished data, 2009).
Psychosocial workers, who usually counsel patients who experience difficulty in making decisions, expressed their concerns about the complexity of decisions that patients have to make and the psychological burden of knowing to carry a mutation for a heritable cancer syndrome.
To determine the heritable differences in immune phenotypes to T. muris, we profiled parasite burden and infection-induced cytokine responses in peripheral blood in 20 BXD lines and both parental strains, C57Bl/6J and DBA/2J.
