Genes affected

WDR19 (HGNC:18340): (WD repeat domain 19) The protein encoded by this gene is a member of the WD (tryptophan-aspartic acid) repeat family, which is a large family of structurally-related proteins known to participate in a wide range of cellular processes. Each WD repeat typically contains about 40 amino acids that are usually bracketed by glycine-histidine and tryptophan-aspartic acid (WD) dipeptides. This protein contains six WD repeats, three transmembrane domains, and a clathrin heavy-chain repeat. Mutations in this gene have been described in individuals with a wide range of disorders affecting function of the cilium. These disorders are known as ciliopathies, and include Jeune syndrome, Sensenbrenner syndromes, Senior-Loken syndrome, combined or isolated nephronophthisis (NPHP), and retinitis pigmentosa (RP). Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Dec 2015]

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 127154). This premature translational stop signal has been observed in individual(s) with nephronophthisis and retinal dystrophy (PMID: 23559409). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Leu214Phefs*5) in the WDR19 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in WDR19 are known to be pathogenic (PMID: 22019273, 23559409, 23683095, 26275793, 27241786, 29068549). -
