A collaborative team of scientists led by Mayo Clinic's Center for Individualized Medicine has discovered 15 additional genetic mutations in the KCNK9 gene that cause a neurodevelopmental syndrome.

Hereditary diseases as well as cancers and cardiovascular diseases may be associated with a phenomenon known as genomic imprinting, in which only the maternally or paternally inherited gene is active.

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 ...

Genomic imprinting means that specific genes inherited from the mother or father are active, whilst the gene inherited from the other parent is inactive. This preferential expression of one allele is ...
