Detailed Description
Statement
Reference

Wnt2L/Wnt2O transheterozygous mutant males exhibit missing or incompletely developed testes. This phenotype is variable, with approximately 10% of the transheterozygous males being fertile.

Mutant embryos do not show salivary gland defects.

With variable penetrance, homozygous males have much smaller testes than wild-type. The hub cells, cyst cells and terminal epithelial cells are present. The germ cell lineage is also present. The outermost pigment layer, which normally covers both the testis and seminal vesicles, is absent. The muscle cell layer of the testis sheath is malformed or incomplete. Testis colour: the testis sheath lacks yellow pigmentation. Homozygotes have held out wings.

No lateral transverse muscle defects are observed in Wnt2L Wnt4C1 double mutant stage 16 embryos.

Wnt2L and Wnt4C1 do not enhance the lateral transverse muscle attachment defects seen in Wnt5400 mutant stage 16 embryos.

Generated in the same screen as Wnt2K, and has the same amino acid replacement, therefore the 2 mutations may not be independent events.
