Perhaps you should try some spelling variations:
decrease during » increase during (Expand search), increases during (Expand search), increased during (Expand search)
decrease atxn2 » decrease and (Expand search), decrease at (Expand search)
atxn2 decrease » and decrease (Expand search), stent decrease (Expand search), any decrease (Expand search)
during pattern » turing pattern (Expand search), turing patterns (Expand search), using pattern (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease atxn2 decrease AND decrease ) OR ( decrease to decrease during pattern ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease atxn2 decrease AND decrease ) OR ( decrease to decrease during pattern ))*.
