G to A nucleotide change at the second or third position of the wild type Trp codon leads to a nonsense mutation (exact site of mutation unspecified). The mutation was annotated at the second base of the codon.
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.
