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 ...

Gregor Johann Mendel, the ‘father of modern genetics’ was born 200 years ago on July 20, 1822. Scientists have advanced in genetics in leaps and bounds because of one individual who pursued in ...

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 ...

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 ...

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 ...

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 ...
