Abstract

Primary ciliary dyskinesia (PCD) is an autosomal-recessive disorder characterized by impaired ciliary function that leads to subsequent clinical phenotypes such as chronic sinopulmonary disease. PCD is also a genetically heterogeneous disorder with many single gene mutations leading to similar clinical phenotypes. Here, we present a novel PCD causal gene, coiled-coil domain containing 151 (CCDC151), which has been shown to be essential in motile cilia of many animals and other vertebrates but its effects in humans was not observed until currently. We observed a novel nonsense mutation in a homozygous state in the CCDC151 gene (NM_145045.4:c.925G>T:p.[E309*]) in a clinically diagnosed PCD patient from a consanguineous family of Arabic ancestry. The variant was absent in 238 randomly selected individuals indicating that the variant is rare and likely not to be a founder mutation. Our finding also shows that given prior knowledge from model organisms, even a single whole-exome sequence can be sufficient to discover a novel causal gene. Primary ciliary dyskinesia (PCD) is a disorder characterised by impaired respiratory cilia function which leads to phenotypes such as chronic sino-pulmonary disease. In this work, we present a novel PCD causal gene CCDC151, which was identified in a single proband using whole-exome sequencing. Our finding also shows that even a single whole-exome sequence can be sufficient to identify a novel causal gene, given priorknowledge from model organisms.
