There are many diseases and disorders that are associated with mosaicism, especially since there are two types; somatic and gonadal. Mosaicism occurs from a mutation during development to only a certain group of cells, not every cell in the body. Chial lists many somatic mosaic...
Benefits of the Human Genome Project
By: Kevin Freeman - 553984
Deoxyribonucleic acid or DNA is the basic template for most living organisms. It is what makes humans individual and distinct or identical twins so similar. However, our own DNA, the human genome, is very complicated and there are many things still not understood. This would...
Scientists find 'master switch' gene for obesity
By: Gene Patterson
There is some good news on the horizon for people that continuously are fighting the "Battle of the Bulge". It seems that scientists have found the 'master switch' gene for obesity. It would be great if this meant that they could simply "turn-off" that switch...
A guide on RNA types
By: Alicia M Prater PhD
Ribonucleic acid, known by its acronym RNA, is a sequence of chemical code complementary to the more famous DNA. Similar to DNA, four nucleotides make up the RNA sequence – adenine (A), uracil (U, the counterpart to thymine, T, in DNA), cytosine (C), and guanine...

The so called Philadelphia chromosome is an abnormal nuclear structure present in most cases of chronic myelogenous leukemia (CML) and to a lesser extent in other types of leukemia, most notably acute lymphocytic leukemia (ALL). The origin of the term Philadelphia chromosome simply reflects...

A genetic disorder can be described as an illness that is caused by abnormalities in the genes or chromosomes. There are some diseases that may be a cross between genetic and environmental factors, such as different types of cancers. Most genetic disorders only affect one...

A chromosome is found in the nucleus of the human cell, the building block of the human body. It contains a linear thread of DNA (deoxyribonucleic acid) and associated proteins. A chromosome carries the genes and plays a major role in transmitting hereditary information. Human...

Von Hippel-Lindau disease (VHL) is a relatively rare genetic disorder, affecting an estimated 10,000 people in the U.S. The inheritance pattern of VHL is autosomal dominant. This means that anyone born with the disease gene has a 50% chance of passing it on...
Mutations that cause laminopathy
By: Alicia M Prater PhD
Laminopathies are genetic disorders caused by mutations in the lamin family of nuclear proteins, lamin A/C. The LMNA gene encodes several lamin proteins, which are classified as type V intermediate filaments and make up the nuclear membrane. The various disorders include types of muscular dystrophy...

The most common polysomy involving the sex chromosomes is a disorder known as Klinefelter's syndrome. Klinefelter's results from the non-disjunction of one or more X chromomosomes during meiosis leading to an abnormal karyotype (chromosome number or structure). The majority of non-disjunction events are believed to...
