Description

Identical insertion of 7.5kb 412 into first exon of 83 nucleotides.

(Fridell et al., 1990)

Insertion of a 412 element between base pairs 1150 and 1151, 36bp downstream of the major transcription start site, and 21bp upstream of the translation start site. The direction of transcription of the 412 element is opposite to the direction of v transcription.
