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]

The c.2276_2280delTGTCT (p.L759Qfs*24) alteration, located in coding exon 16 of the KIAA0586 gene, consists of a deletion of 5 nucleotides at nucleotide positions 2276 to 2280, causing a translational frameshift with a predicted alternate stop codon after 24 amino acids. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD). Based on the available evidence, this alteration is classified as pathogenic. -

For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in KIAA0586 are known to be pathogenic (PMID: 26096313, 26166481). This variant has been reported in the literature in an individual with Joubert syndrome (PMID: 26096313). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Leu888Glnfs*24) in the KIAA0586 gene. It is expected to result in an absent or disrupted protein product. -
