N2 - Joubert syndrome (JS) is a genetically heterogenous disorder of nonmotile cilia with a characteristic “molar tooth sign” on axial brain imaging. Clinical features can include developmental delay, kidney failure, liver disease, and retinal dystrophy. Prospective growth and measurement data on 170 individuals with JS were collected, including parental measurements, birth measurements, and serial measures when available. Analysis of growth parameters in the context of hepatorenal disease, genotype, and other features was performed on 100 individuals assessed at the National Institutes of Health Clinical Center. Individuals with JS had shorter stature despite normal growth velocity and were shorter than predicted for mid-parental height. Individuals were lighter in weight, resulting in a normal body mass index (BMI). Head circumference was larger, averaging 1.9 Z-scores above height. At birth, head circumference was proportional to length. Individuals with variants in CPLANE1 had a larger head circumference compared to other genotypes; individuals with evidence of liver disease had lower weight and BMI; and individuals with polydactyly had shorter height. Here we present growth curves and physical measurements for Joubert syndrome based on the largest collection of individuals with this disorder to aid in clinical management and diagnosis.
