Weaver-Williams syndrome is a multiple congenital anomalies syndrome characterized by moderate-to-severe intellectual disability, decreased muscle mass, microcephaly, facial dysmorphism (prominent ears, midfacial hypoplasia, small mouth and cleft palate), clinodactyly of the fingers, delayed osseous maturation and generalized bone hypoplasia. The syndrome has been described in a brother and sister and an autosomal recessive mode of inheritance has been suggested. There have been no further descriptions in the literature since 1977. |

Microbrachycephaly-ptosis-cleft lip syndrome is characterized by the association of intellectual deficit, microbrachycephaly, hypotelorism, palpebral ptosis, a thin/long face, cleft lip, and anomalies of the lumbar vertebra, sacrum and pelvis. It has been described in two Brazilian sisters. Transmission appears to be autosomal recessive. |

Gastrointestinal tract involvement (malrotation, gastroesophageal reflux etc.) and cardiac involvement (coarctation of aorta, pulmonary artery stenosis, etc.) have also been reported. An overlap with Kabuki syndrome is debated. |
