Description

Single base deletion within the open reading frame, at or very close to the calcium binding site at the start of the cadherin like domain, resulting in a frameshift.

(Myers and Kidd, 2019.3.22)

Out of frame deletion predicted to result in a truncated Ret protein.

Comment:

RetLM3 is a 1 base deletion in Ret in the same location as RetLM2 that leads to a frameshift.

      Statement
      Reference

      RetLM3 homozygous larvae, RetLM3/RetLM1 and RetLM2/RetLM3 transheterozygous larvae hatch normally but show a range of feeding defects, as compared to controls: a foraging phenotype in which larvae move away from a central food source; accumulation of food in the oesophagus; reduced/absence of food in the midguts and absence of food in the oesophagus. RetLM1 homozygous larvae are frequently immobile or sluggish in response to touch, as compared to controls.
