Cytology
Description

Deletion that extends from the 5'UTR to the first intron of Syx4, removing the first exon and thus the translation start site for the A isoform (coordinates X:2743312..2743832 , release 6 genome, are deleted). Generated by imprecise excision of P{EPgy2}Syx4EY00005; more than 1kb of the original insertion remains.

Comment:

Deletion resulting from the imprecise excision of P{EPgy2}Syx4EY00005 removes X:2743312..2743832 , release 6 genome coordinates. More than 1 kb of P element sequences remain at the site of the deletion.
