Understanding Human Diseases through Genetic Research

Genetic research reports findings of molecular interactions, mutations and genes to understand human disease. A lot of diseases, including cancer, psychiatric illness and cardiovascular diseases arise from interactions between environmental encounters and genetics. Genetic advancements are made by scientists in regards to cancer and breast cancer specifically through research from concept to clinical stages. Advancements are made in the Epigenetics and Chromatin in Cancer and cancer vulnerabilities.
Genetic Disorders are identified in four types, which are Single-gene or monogenic, multifactorial, mitochondrial and chromosomal.
Single-gene disorders are caused by mutations occurring in a gene’s DNA sequence. Genetic research shows that there are over six thousand single-gene disorders and samples are hereditary hemochromatosis, Huntington’s disease, Marfan syndrome, sickle cell anemia and cystic fibrosis.
Multifactorial or complex disorders are a combination of multiple gene mutations and environmental factors. Chronic examples are Alzheimer’s disease, high blood pressure, heart disease, obesity, cancer, diabetes and arthritis.
Mitochondrial is quite rare and caused by no chromosomal DNA mutations of mitochondria.
Chromosomal a combination of protein and DNA chromosomes develop abnormalities.
Genetic advancements allows for consumers to do their own genetic testing. The tests range from drug responses, disease risk, tests of ancestry and more. With genetic research so complex a field, consumers looking for a genetic testing company and product they can trust can be a daunting experience.
Looking for the right company, take into consideration its legitimacy through consumer watchdogs and reviews. The chosen company must allow downloading of raw genotypes after testing. Direct genetic research tests to consumers should be treated as informative and not diagnostically and if any doubt arise result must be followed up with experts.
A reputable company will provide a result print-out, which can be examined and if necessary presented to clinicians as general doctors may find complex information from a genome scan difficult.

Viral and Host Genetic Factors Regulating HIV-Associated CNS Disease (R01)

Executive Summary Purpose. The National Institute of Mental Health (NIMH) and The National Institute of Neurological Disorders and Stroke (NINDS) solicit research grant applications to support studies focused on viral and host genetic factors , involved in HIV-1 Associated Neurocognitive Disorders (HAND) in the setting of highly active anti-retroviral therapy (HAART). Recent clinical studies indicate that over 50% of HIV-infected patients manifest HAND despite receiving… more

What is genomics and post genomics?

Genomics encompasses everything from sequencing genomes, ascribing functions to genes, and studying the structure of genes (gene architecture). Post-genomics takes these techniques further,  studying patterns in how genes are transcribed into messenger RNA, the chemical that carries the instructions for forming proteins (transcriptomics), in the way genes are expressed as proteins (proteomics), and in how they influence the chemicals that control our cellular biochemistry and… more
