♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

mortality/aging

lethality throughout fetal growth and development ( J:216825 )

• viable until late in gestation

limbs/digits/tail

absent limbs ( J:216825 )

• embryos lack limbs

• however, a presumptive hindlimb bud is present up to approximately E12.5

reproductive system

primary sex reversal ( J:216825 )

• XY embryos exhibit complete gonadal sex reversal as evidenced by ovarian morphology and expression of ovarian markers and absence of Sertoli cell makers at E14.5

• entry of germ cells into meiosis is seen at E14.6, indicating germ cell sex-reversal

respiratory system

pulmonary hypoplasia ( J:216825 )

• hypoplastic lungs
