Based on preliminary data from the OMF-funded Severely Ill Patient Study (SIPS), which found several genes which may carry mutations in PwME.  These mutations may cause enzymes which process important metabolites to slow down and cause a metabolic trap, which could explain some symptoms in ME/CFS.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;metabolite&#039;&#039;&#039; - a substance produced by, or involved in metabolism.&lt;br /&gt;

Based on preliminary data from the OMF-funded Severely Ill Patient Study (SIPS), which found several genes which may carry mutations in PwME.  These mutations may cause enzymes which process important metabolites to slow down and cause a metabolic trap, which could explain some symptoms in ME/CFS.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;metabolite&#039;&#039;&#039; - a substance produced by, or involved in metabolism.&lt;br /&gt;

Based on preliminary data from the OMF-funded Severely Ill Patient Study (SIPS), which found several genes which may carry mutations in PwME.  These mutations may cause enzymes which process important metabolites to slow down and cause a metabolic trap, which could explain some symptoms in ME/CFS.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;metabolite&#039;&#039;&#039; - a substance produced by, or involved in metabolism.&lt;br /&gt;
