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 ...

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 ...

The COVID-19 pandemic gave us tremendous perspective on how wildly symptoms and outcomes can vary between patients experiencing the same infection. How can two people infected by the same pathogen ...

All people have two copies of every gene – one copy inherited from each parent. The NF1 gene mutation is dominant, which means that only one of the two copies of the gene needs to have the mutation to ...

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 ...

I recently underwent genetic testing to see if I had any mutations that could be associated with an increased cancer risk. When I received my genetic testing kit in the mail, I quickly opened the ...

Research on Tourette’s indicates that the condition is strongly influenced by inherited genetic factors, with environmental factors also contributing to its development. Tourette syndrome is a ...
