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]

For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with KIAA0586-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Met1415Alafs*6) 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). -
