UASt regulates expression of a Hsap\PTPN11 R498W variant found in patients with a RASopathy.
Expressing Hsap\PTPN11R498W.UAS under the control of Scer\GAL4ptc.PU leads to altered wing vein material patterns outside of the ptc expression domain. Expression under the control of Scer\GAL4C-765 leads to an increase in cross-veins between L1 and L4.
