Imprecise excision of P{EPgy2}Neurl4EY12221. The first exon and a portion of the second exon are deleted, as well as 409 bp upstream of the transcription start site of Neurl4.
Approximate boundaries of a deletion resulting from the imprecise excision of P{EPgy2}Neurl4EY12221. The deletion was reported to remove exon 1 and a portion of exon 2 of Neurl4 as well as 409 bp upstream of the Neurl4 transcription start site.
Neurl4Δ1 mutants display a dominant misshapen primordial germ cells (PGC) in well over half of the embryos from heterozygous mothers.
