ABSTRACT
Retinitis pigmentosa (RP), the most common form of inherited retinal degeneration, is associated with different groups of genes, including those encoding proteins involved in centriole and cilium biogenesis. Exome sequencing revealed a homozygous nonsense mutation [c.304_305delGA (p. D102*)] in POC5, encoding the Proteome Of Centriole 5 protein, in a patient with RP, short stature, microcephaly and recurrent glomerulonephritis. The POC5 gene is ubiquitously expressed, and immunohistochemistry revealed a distinct POC5 localization at the photoreceptor connecting cilium. Morpholino-oligonucleotide-induced knockdown of poc5 translation in zebrafish resulted in decreased length of photoreceptor outer segments and a decreased visual motor response, a measurement of retinal function. These phenotypes could be rescued by wild-type human POC5 mRNA. These findings demonstrate that Poc5 is important for normal retinal development and function. Altogether, this study presents POC5 as a novel gene involved autosomal recessively inherited RP, and strengthens the hypothesis that mutations in centriolar proteins are important cause of retinal dystrophies.
