♀	phenotype observed in females

N	normal phenotype

reproductive system

abnormal maternal decidual layer morphology ( J:233595 )

• abnormal primary decidual zone (PDZ) development at 6 dpc

• PDZ was absent in some implantation sites with the embryo entrapped within the intact epithelium at 6 dpc

abnormal embryo attachment ( J:233595 )

• uteri either failed to show or had very weak endometrial vascular permeability at the site of blastocyst attachment at 5 dpc

• unattached blastocysts were recovered from uteri at 5 dpc

• defects in crypt formation

• some blastocysts situated within the primary lumen

reduced female fertility ( J:233595 )

• only 29% of plug-positive females produce a (small) litter

• high resorption rates on 12 dpc

decreased litter size ( J:233595 )

• in the few fertile mice

embryo

abnormal maternal decidual layer morphology ( J:233595 )

• abnormal primary decidual zone (PDZ) development at 6 dpc

• PDZ was absent in some implantation sites with the embryo entrapped within the intact epithelium at 6 dpc

Ror1^tm1.1Meg/Ror1^tm1.1Meg Ror2^tm1.1Meg/Ror2^tm1.1Meg H2az2^{Tg(Wnt1-cre)11Rth}/0 embryos exhibit sympathetic axon branching defects

nervous system

abnormal sympathetic neuron innervation pattern ( J:182150 )

• sympathetic innervation defects are seen in several target organs at E17.5

• defects are similar to those in Wnt5a null mice

• however, sympathetic chain ganglia appear grossly intact
