Liberfarb syndrome

Synonyms
SPONDYLOEPIMETAPHYSEAL DYSPLASIA, LIBERFARB TYPE; Short stature-skeletal dysplasia-retinal degeneration-intellectual disability-sensorineural hearing loss syndrome

Summary

Liberfarb syndrome is a progressive disorder involving connective tissue, bone, retina, ear, and brain. Patients exhibit severe short stature and scoliosis with thoracic kyphosis and lumbar hyperlordosis. Severe joint laxity results in dislocations of elbows, hips, and knees. Eye findings are consistent with early-onset retinal degeneration, and there is moderate to severe early-onset hearing loss. Microcephaly is apparent by school age, and patients exhibit developmental delay and intellectual deficits (Peter et al., 2019). Clinical variability has been observed, with some patients presenting differences in the severity and location of skeletal dysplasia involvement as well as variation in other features of the syndrome (Girisha et al., 2019; Zhao et al., 2019).
