Can a microform cleft be either a cleft lip and/or a cleft palate?

I presumed microform cleft refered to only a cleft lip. Now I am wondering if it could pertain to a cleft palate.  A woman friend believes Joaquin Phoenix imicroform cleft is from a cleft palate.   If there is no such thing as a microform cleft palate then he must be born with cleft lip.   If microform cleft palates do occur there is no certainty his cleft is a cleft palate.   One can prove it isn't but the other can't prove it is.
