For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its ...

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 ...

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 ...

Forty years ago, a postdoctoral researcher named James McGrath who would go on to spend more than three decades as a clinical geneticist and research scientist at Yale, made a discovery that advanced ...

Hemophilia is a bleeding disorder that can affect the blood’s ability to clot properly. In most cases, people inherit the gene variations for hemophilia in an X-linked recessive inheritance pattern.

Hypermobile Ehlers–Danlos syndrome (hEDS) is one of the most common heritable connective tissue disorders. Early estimates have reported that this genetic disorder affects at least one in 5,000 ...
