A Jew that converts to another religion.
An Apostate Jew
An apostate.
What is this question all about?
The Yiddish word for a Jew who converts to Christianity is "apikores," which carries a derogatory connotation.
* A person who renounces his former religious beliefs is an apostate. * In most cases, ..."smart"!
Julian the Apostate was born in 331 or 332.
A Jew is someone born to a Jewish mother or who has converted to Judaism; Jewish tradition does not recognize "half Jewish" or "partly Jewish" as a status. You either are or you are not. A Jew who abandons Judaism and adopts another religion is an apostate. It is important to understand, though, that to be Jewish is to be accepted as a Jew by the Jewish community. It is not just between you and God. So, conversion to Judaism involves coming learning enough to come before a rabbinical court and be accepted as a Jew. There are also ritual requirements such as circumcision and dunking in a mikvah. For an apostate to return to Judaism, mere private renunciation of the other religion is not enough, it is also necessary to patch up differences with the Jewish community.
By whom? They do not consider themselves to be apostate, certainly not as a whole. So your question needs to tell us who is considering them to be apostate.

I suppose you call them either a Jew or a Muslim since Judaism and Islam are separate religions and you cannot be both. There is also no specific term for a Jew who converted to Islam or a Muslim who converted to Judaism in either religion. (Apostate is general term for abandoning your faith.)
According to Judaism, a Jew's nature as a Jew is part of his make-up and does not "wax and wane" with his belief. The nature of being part of the Jewish Nation - Jewish Identity, is not contingent on faith. (To a religious Jew, the question is as absurd as asking "How can an Italian who does not have faith in Catholicism resume his Italian-ness?") It is for this reason that Judaism does not recognize de-conversion or apostasy. If a Jewish person who has been atheist or the adherent of a different faith wishes to rediscover their Judaism, there are numerous organizations that can assist with that and are sponsored by the different Jewish movements.
