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.
Features include: Narrow forehead, Palmoplantar cutis laxa, Strabismus, and Hearing loss (hearing impairment) and 27 more.
