I think the question asks 'if it binds to RXR, what happens?'

The retinoid X receptor (RXR1) is an intriguing and essential member of the steroid/thyroid hormone superfamily of nuclear receptors (NRs) that predominately function as transcription factors with roles in development, cell differentiation, metabolism, and cell death

which means its related with development etc

bend_nbme_over  Definitely a poorly worded question for sure +

niboonsh  yea it was a dumbass question, whoever is writing these questions is undoubtedly a crazy genius but homeboy (or homegirl...homeperson?) needs a few grammar lessons. +4  
yex  I agree. We know that it is a teratogen, but how does that question directs you to think about teratogenic effects instead of something physiologic? +5  
dr_jan_itor  The questions in the NBMEs by default are reject questions. So highly selective to be awful questsions. I am recieving regular heads up that the stems on the real thing lately are like 10-12 lines long. So these questions are not anywhere near like the test. NBME has f'd us good for this particular round of practice forms. +
