Population frequency — 1:90 000 (a typical cleft hand), 1:160000 (an atypical cleft hand).

Ratio of floors — M1:Zh1.

The mode of inheritance — cases of the isolated lack of one finger of a brush usually sporadic, a cleft hand, accompanying with similar deformation of foot, Is inherited on autosomal dominantly type with various expressivity and penetrance, cases of autosomal and recessive inheritance are described.
