摘要

Mainzer-Saldino syndrome (MSS) is a rare disorder characterized by phalangeal cone-shaped epiphyses, chronic renal failure, and early-onset, severe retinal dystrophy. Through a combination of ciliome resequencing and Sanger sequencing, we identified IFT140 mutations in six MSS families and in a family with the clinically overlapping Jeune syndrome. IFT140 is one of the six currently known components of the intraflagellar transport complex A (IFT-A) that regulates retrograde protein transport in ciliated cells. Ciliary abundance and localization of anterograde IFTs were altered in fibroblasts of affected individuals, a result that supports the pivotal role of IFT140 in proper development and function of ciliated cells.
