The empty row in the print you see is because the index has a name - Gene.name (This is not a real row in the DataFrame though) . If you don't want that row , I believe you would need to do away with the name. Example -

df.index.name = None

Demo -

In [6]: df = pd.DataFrame([[1,2,3,4],[1,2,3,4]]).set_index(0)

In [7]: df
Out[7]:
   1  2  3
0 <-------------------------- Name of the index for this DataFrame
1  2  3  4
1  2  3  4

In [10]: df.index.name=None

In [11]: df
Out[11]:
   1  2  3
1  2  3  4
1  2  3  4
