For more than a century, heredity has been framed through the tidy logic of Mendel’s pea plants: traits pass from parent to ...

Jaime Murillo, MD, explores genetic inheritance patterns of Lp(a) from childhood to adulthood, highlighting stability, factors affecting measurement, and awareness challenges among those in the health ...

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 ...

Although schwannomatosis is a genetic condition, the inheritance patterns for this disorder are complex and much less clear than for both NF1 and NF2. Some cases of schwannomatosis are familial, with ...

Scientists have long known that the DNA code in genes is not the only way to pass genetic traits from parents to offspring. "Epigenetic" marks—chemical modifications to DNA that don't change the DNA ...

Von Willebrand disease (VWD) is a bleeding disorder in which the blood does not clot as it should. Usually, people have VWD due to their genes, which may come from a male or female parent. Blood ...

Retinitis pigmentosa (RP) is an eye condition that can be genetic. In this way, people usually need to inherit two copies of a genetic variation that causes RP, one coming from each parent. RP may ...
