Genes affected

KIAA0586 (HGNC:19960): (KIAA0586) This gene encodes a conserved centrosomal protein that functions in ciliogenesis and responds to hedgehog signaling. Mutations in this gene causes Joubert syndrome 23. Alternative splicing results in multiple transcript variants and protein isoforms. [provided by RefSeq, Aug 2016]

This sequence change creates a premature translational stop signal (p.Gln288Argfs*7) in the KIAA0586 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in KIAA0586 are known to be pathogenic (PMID: 26096313, 26166481, 26386044). This variant is present in population databases (rs770566897, gnomAD 0.008%). This premature translational stop signal has been observed in individual(s) with Joubert syndrome (PMID: 26096313). ClinVar contains an entry for this variant (Variation ID: 204596). For these reasons, this variant has been classified as Pathogenic. -
