derepression of heterchromatic gene silencing

Genes normally silenced within heterochromatin are abnoramally de-repressed and exhibit expression, unlike controls.

microtubule nucleation variant

Any variation that alters the characteristic de novo formation of a microtubule compared to control.

lipid synthesis defective

The de novo synthesis of any lipid species is reduced compared to that observed in control animals.

D lineage variant

The descendants of the D blastomere exhibit any variation in developmental programs compared to their counterparts in control animals.

aberrant posteriorly-directed neurite

Any neurite that is extended towards the posterior of the animal from neurons that in wild-type animals make only anterior projections (e.g. D-type neurons in C. elegans).
