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]

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 19, 2024	This sequence change replaces asparagine, which is neutral and polar, with lysine, which is basic and polar, at codon 1054 of the KIAA0586 protein (p.Asn1054Lys). This variant is present in population databases (rs199537542, gnomAD 0.03%). This variant has not been reported in the literature in individuals affected with KIAA0586-related conditions. ClinVar contains an entry for this variant (Variation ID: 542185). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt KIAA0586 protein function with a positive predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

DNA sequence analysis of the KIAA0586 gene demonstrated a sequence change, c.3162C>A, in exon 23 that results in an amino acid change, p.Asn1054Lys. This sequence change does not appear to have been previously described in patients with KIAA0586-related disorders and has been described in the gnomAD database with a low population frequency of 0.030% in non-Finnish European subpopulation (dbSNP rs199537542). The p.Asn1054Lys change affects a moderately conserved amino acid residue located in a domain of the KIAA0586 protein that is not known to be functional. In-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL) provide contradictory results for the p.Asn1054Lys substitution. Due to these contrasting evidences and the lack of functional studies, the clinical significance of the p.Asn1054Lys change remains unknown at this time. -
