snRNA:U1:82Ea does not appear to be present in the D.melanogaster strain used for sequencing the genome; only one copy of a U1 snRNA gene (CR32862) has been detected at 82E in the sequenced strain, although 3 copies have previously been reported in clones derived from Oregon R flies - snRNA:U1:82Eb, snRNA:U1:82Ec and snRNA:U1:82Ea (FBrf0052749). The copy present in the sequenced strain appears to correspond to snRNA:U1:82Eb, while snRNA:U1:82Ec and snRNA:U1:82Ea appear to be missing from the sequenced strain (see FBrf0128209).

5' splice site mutation of w can be suppressed by compensatory mutations in the 5' end of U1, both molecularly in transformed cells and phenotypically in transformed flies.
