The Board has granted service connection for mast cell activation syndrome (MCAS) as secondary to the Veteran's service-connected posttraumatic stress disorder (PTSD). The evidence is at least in equipoise that MCAS was aggravated by PTSD.
The deciding factor: The medical opinion provided by Dr. I.N., M.D. FACP, FCCP supports a connection between the service-connected PTSD and the current mast cell activation syndrome (MCAS), creating an equipoise situation which must be resolved in favor of the Veteran.
