Your DNA contains millions of genetic variants that interact with each other in ways that affect whether diseases such as ...

Doug Whitney, 76, carries a rare PSEN2 genetic mutation that causes early-onset Alzheimer's but shows no cognitive decline ...

A study published in Science reveals a cellular mechanism involved in the inheritance of genetic mutations. The study also ...

IgA nephropathy has a complex hereditary pattern. You may not develop it unless you inherit multiple risk genes and also ...

Genetic disorders can occur due to mutations in one gene (monogenic), multiple genes (multifactorial inheritance), and mutation in one or more chromosomes. Point mutations are where one nucleotide in ...

Huntington’s disease (HD) is one of those rare conditions that affects not just the patient but the entire family—medically, emotionally and genetically. This inherited brain disorder causes gradual ...

As more people start to opt for genetic carrier testing ahead of conception, doctors and parents-to-be are facing difficult ...

Many babies enter the world with silent metabolic or genetic conditions. Today, standard newborn screening can check for some ...

In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...

Researchers have identified a new genetic cause of hereditary optic atrophy—a condition that leads to gradual vision loss—by discovering a previously unknown mutation in the PPIB gene. T ...

One gene causes one trait or a specific illness. When doctors use genetics, it's usually to try to identify a disease-causing ...
