The P{EP}LamCEP2199 insertion maps within the first intron of LamC and also within ttv (LamC is nested within the fifth intron of ttv).
The P{EP}LamCEP2199 insertion maps within both LamC and ttv (nested genes on opposite strands).
Expression via Scer\GAL4fkh.PH produces a weakly penetrant and variable phenotype in the embryonic salivary gland.
