In Russian we have a word "отродясь/отроду" that means "since birth". Is there an English one-word to mean "since birth"? I do understand that depending on context, I can use some specific word.
I mean that instead of saying, "I never heard of it" I would like to say something like, "I didn't hear of it since birth" but shorter.
To compare, in Russian it's four words, "Отродясь этого не слышал".
Edit: The Russian word has a synonym "сроду" which is an absolute equivalent.

I think you have answered your own question. In idiomatic English we would render it with never: "I've never heard of it." (perfect tense works well here). That's 6 words, only two more than Russian, which is not bad for an analytic language like English.
