text: # List of gene families
  
  This is a list of gene families or gene complexes, i.e. sets of genes which are related ancestrally and often serve similar biological functions. These gene families typically encode functionally related proteins, and sometimes the term gene families is a shorthand for the sets of proteins that the genes encode. They may or may not be physically adjacent on the same chromosome.
