Description

UASp regulatory sequences drive expression of csw containing the amino acid replacement T592M (this mutation is equivalent to the T468M mutation in the human ortholog Hsap\PTPN11, which is a mutation associated with LEOPARD syndrome in humans).

FlyBase curator comment: The mutation in cswT468M.Scer\UAS.P\T is equivalent to the loss-of-function T468M mutation in the human ortholog Hsap\PTPN11, which is associated with LEOPARD syndrome in humans. Although the mutant protein had no phosphatase activity it resulted in gain-of-function ectopic wing vein phenotype in Drosophila; it is not clear how this relates to phenotypes observed in LEOPARD syndrome.

Detailed Description
Statement
Reference

Expression of cswT468M.Scer\UAS under the control of Scer\GAL4tub does not affect viability or fertility. While expression does not appear to affect early development, approximately 20% of Scer\GAL4tub-cswT468M.Scer\UAS adult flies display ectopic wing veins, mainly in the peripheral area of L2 and the posterior cross vein.

Flies expressing cswT468M.Scer\UAS under the control of Scer\GAL4tub do not exhibit altered photoreceptor formation or ommatidial rotation.
