COMMENTS.
In healthcare, a differential diagnosis (DDx) is a method of analysis that distinguishes a particular condition from others that present similar clinical features. A mnemonic common in healthcare is: VINDICATEM is shown ABOVE.
The “Table of Consanguinity (bloodline)” is shown BELOW. Any trait has varying degrees of genetic determinant. We live in an era direct-to-consumer DNA companies (Ancestry, Familytree, 23&Me … etcetera). OMIM (Online Mendelian Inheritance in Man’) over free access to the human genome. Differential diagnosis (DDx) is updating the OMIM daily, and the value of information increases.
