UASp regulatory sequences drive expression of csw containing the amino acid replacement equivalent to the T73I mutation in the human ortholog Hsap\PTPN11, which is associated with Noonan syndrome and leukemia.
C2103730T
T195I | csw-PB
Analogous mutation in human PTPN11 implicated in Noonan syndrome 1 and juvenile myelomonocytic leukemia; mutation carried on in vitro construct; site of nucleotide substitution in fly gene inferred by FlyBase curator based on reported amino acid change.
