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 ...

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 ...

“Our study showed that the search for recessive effects in genome-wide association studies can be worthwhile, especially if somewhat rarer genetic variants are included, as is the case in the FinnGen ...

We identified a large family segregating an uncomplicated and early onset form of HSP. Exome sequencing revealed homozygosity for a novel ATL1 missense variant in the six affected family members, ...

Discover the fascinating world of Mendelian genetics, where the inheritance of traits from parents to offspring follows predictable patterns. This concept explains how genetic information is ...

Purpose: Recurrence of lethal osteogenesis imperfecta in families results from either dominant (parental mosaicism) or recessive inheritance. The proportion of these two mechanisms is not known, and ...

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 ...

Some health problems are passed down through families. There are different ways this can happen. To have a child born with what’s called an “autosomal recessive disease” like sickle cell disease or ...
