st: Heavy representation in a sample

Hello,
I would like to know if there is any econometric problem when making an
OLS regression using a sample that is heavily represented by a subset
within a variable? For instance, we are using country legal systems as
an explanatory variable : 65% is Anglo-Saxon and the rest is divided
between French, German and Scandinavian. Is there any econometric
problem using such a sample? If so, what are the methods to correct it?
Thank you,
Claude
