Nucleotide change:

T24750609A

Reported nucleotide change:

T578A

Comment:

Position of mutation on reference sequence inferred by FlyBase curator. Difference beteween actual and reported nucleotide substitution due to different start site used by authors. Mutation is in splice donor in intron 3.

      Moderate tld phenotype.

      (Childs and O'Connor, 1994)

      Moderate ventralised phenotype. Defective movements of the germ band: due to loss of the amnioserosa and because the dorsalmost cells have acquired the lateral fate of the dorsal ectoderm. Dorsal cell fates are deleted and ventrolateral mitotic domains are expanded.
