ABSTRACT
Bardet-Biedl syndrome (BBS) is a rare ciliopathy characterized by rod-cone dystrophy, postaxial polydactyly, truncal obesity and renal anomalies with autosomal recessive inheritance. We describe a 6-year-old male with early onset retinal dystrophy, postaxial polydactyly, truncal obesity and motor delays. Exome sequencing revealed a homozygous variant predicted to affect splicing of the IFT74 gene, c.1685-1G > T. This is the third patient with BBS due to variants predicting loss of function in IFT74. All three patients have had retinal dystrophy, polydactyly, obesity, developmental differences, and a notable lack of renal anomalies. We recommend that IFT74 is added to gene panels for the diagnosis of BBS.
