Extension of the cleft lip phenotype: the subepithelial cleft.

American journal of medical genetics - 1 Oct 1993

Martin R A, Jones K L, Benirschke K

Abstract excerpt

We present a previously undescribed occult malformation of the upper lip manifest by discontinuity of the orbicularis oris muscle. The relationship of this defect to our current concept of abnormal maxillary process development is discussed along with a proposal to extend the cleft lip phenotype.
