  • bilateral cleft lip and palate (52%)
  • unilateral cleft lip and palate (31%)
  • isolated cleft palate (17%)

- paramedian lip pits

- ankyloblepharon (18478600)

- coronal hypospadias (18478600)

A positive family history was found in 53.1% of the patients. The size, shape, location, and depth of the pits varied among patients.

  • allelic to popliteal pterygium syndrome (PPS)
