      One copy of Su(var)327unspecified strongly suppresses position effect variegation (PEV) at the w locus caused by In(1)wm4.

      One copy of Su(var)327unspecified is unable to suppress the telomeric position effect (TPE) in stocks carrying a variegating P{hsp26-pt-T}39C-5 insertion at the telomere of the left arm of chromosome two.

      (Doheny et al., 2008)

      Dominant suppressor of position effect variegation in eye pigment caused by In(1)wm4 or In(2R)bwVDe2. Dominant suppressor of position effect variegation at the Sb locus caused by T(2;3)SbV. The suppressor effect on the variegation caused by In(1)wm4 is substantially reduced or eliminated entirely in male XO flies lacking a Y chromosome.
