Peters plus syndrome is characterized by anterior chamber eye anomalies, short limbs with broad distal extremities, characteristic facial features, cleft lip/palate, and variable developmental delay / intellectual disability. The most common anterior chamber defect is Peters' anomaly, consisting of central corneal clouding, thinning of the posterior cornea, and iridocorneal adhesions. Cataracts and glaucoma are common. Developmental delay is observed in about 80% of children; intellectual disability can range from mild to severe.

Lathosterolosis is characterized by global developmental delays, intellectual disability, microcephaly, characteristic facial features (bitemporal narrowing, sloping forehead, epicanthal folds, ptosis, downslanting palpebral fissures, anteverted nares, broad nasal tip, long philtrum, high-arched palate, and micrognathia), cataracts, digit anomalies (postaxial polydactyly, toe syndactyly), and liver disease. The severity of liver disease can range from asymptomatic elevation of liver enzymes to cirrhosis and liver failure.
