Discussion:

Added MEDLINEPLUS Genetics data which resulted in the addition of a new relationship attribute (RELA) and new attributes (ATN).

 

The Genetics data covers 3 areas:

causes, and inheritance of more than 1300 genetic conditions

(2) genes- the function of more than 1400 genes and how changes in

these genes are related to health conditions; and

(3) human chromosomes and mitochondrial DNA (mtDNA).
