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 ...

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 ...

Genetic information in the DNA and modifications, such as DNA methylation, define the epigenetic landscape and phenotype and show both Mendelian and non-Mendelian heredity. Scientists have long known ...

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 ...

Study results regarding the clinical spectrum and inheritance pattern of GDF2 pathogenic variants suggest incomplete penetrance and/or variability of expressivity with a semi-dominant pattern of ...

It has been hypothesized that the inheritance of epigenetic traits, such as DNA methylation, may be more prevalent than is currently established 1,2. This phenomenon could help explain poorly ...
