Juberg-Hayward syndrome (JHS) is characterized by cleft lip and palate, rhizomelia of the upper limbs with limited elbow extension due to humeroradial synostosis or dislocation of the radial head, and digital anomalies, including shortened thumbs and index and fifth fingers. Microcephaly has been observed in some patients (Kantaputra et al., 2020). [from OMIM]

ESCO2 spectrum disorder is characterized by mild-to-severe prenatal growth restriction, limb malformations (which can include bilateral symmetric tetraphocomelia or hypomelia caused by mesomelic shortening), hand anomalies (including oligodactyly, thumb aplasia or hypoplasia, and syndactyly), elbow and knee flexion contractures (involving elbows, wrists, knees, ankles, and feet [talipes equinovarus]), and craniofacial abnormalities (which can include bilateral cleft lip and/or cleft palate, micrognathia, widely spaced eyes, exophthalmos, downslanted palpebral fissures, malar flattening, and underdeveloped ala nasi), ear malformation, and corneal opacities. Intellectual disability (ranging from mild to severe) is common. Early mortality is common among severely affected pregnancies and newborns; mildly affected individuals may survive to adulthood. [from GeneReviews]
