Cleft lip and palate in combination; cleft lip (cheiloschisis) and cleft palate (palatoschisis), individually.

When they are poisoned by C. maculatum during the fetus's organ formation period, the offspring is born with malformations, mainly palatoschisis and multiple congenital contractures (MCC; frequently described as arthrogryposis).

Cleft lip (cheiloschisis) and cleft palate (palatoschisis), which can also occur together as cleft lip and palate, are variations of a type of clefting congenital deformity caused by abnormal facial development during gestation.
