Gene mutation and/or ic polymorphism is a normal occurrence, usually without grave consequences, that contributes to those traits that establish our individuality.
ic polymorphism:基因多态性
3
医学资源
According to numerous information available, ic diseases can be categorized into three major groups: chromosomal disorders, monogenic or single-gene disorders, and polygenic or multifactorial disorders.
chromosomal:染色体;monogenic/single-gene:单基因;polygenic/multifactorial多基因

医学资源
Polygenic or multifactorial disorders result from multiple ic and/or ic factors that do not conform to traditional Mendelian inheritance pattens, which are different in monogenic disorders.
ic:后生的;Mendelian inheritance:孟德尔遗传;

医学资源
The pathogenic nature of methylation is illustrated by the observation that for many tumor suppressor genes.
methylation:***化;pathogenic:病原的 Hybridization:杂交

医学资源
The detection of methylated sequences in DNA derived from the plasma or serum by all kinds of sensitive techniques is a potentially important early detection and monitoring method for cancer.
plasma or serum:血浆或血清
potentially:潜在地

医学资源
DNA alterations have been detected in patients with small or even in situ lesions, indicating that tumor DNA is shed into circulation early in the disease.
alterations:改变,更改;in situ:在原来的位置;
lesion:机能障碍;

医学资源
Our ever broadening insights into the molecular basis of disease processes continue to provide an opportunity for the clinical laboratory to develop and implement new and novel approaches for diagnosis, monitoring, drug resistance and prognostic assessment of human diseases.
Implement:实施;prognostic:预兆
