W369term

Comment:

G to A nucleotide change at the second or third position of the Trp codon leads to a nonsense mutation (exact site of mutation unspecified). Site of nucleotide substitution in mutant inferred by FlyBase based on reported amino acid change.

Comments on Models/Modifiers Based on Experimental Evidence ( 1 )
 

A neurodegenerative disorder has been ascribed to a loss of function mutation of Nrd1 in a patient. Mutations in two known disease-related genes have also been identified in this patient but those have either been reported as benign or their known clinical symptoms do not match the phenotype of the patient.

Detailed Description
Statement
Reference

Adult flies with Nrd1W369X mutant retinal somatic clones show age-progressive loss of synaptic transmission in photoreceptor cells characterized by loss of on- and off-transients in electroretinogram readings compared to wild-type controls.

Reference

The pupal lethality of the Nrd1W369X mutants can be rescued by expression of Hsap\NRDCScer\UAS.T:SV5\V5 but not Hsap\NRDCM636Vstop.Scer\UAS.T:SV5\V5 under the control of Scer\GAL4da.G32 in the mutant background.

Comments

The pupal lethality of the Nrd1W369X mutants can be rescued by combination with any of the following :Nrd1+t5, Nrd1+tCH322-77E05 or Dp(1;3)DC245 or by expression of Nrd1Scer\UAS.T:SV5\V5 (but not Nrd1Scer\UAS.T:Disc\RFP-mCherry) under the control of Scer\GAL4da.G32 in the mutant background.
