Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong
The NM_001329943.3(KIAA0586):c.100G>A(p.Val34Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000316 in 1,613,964 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V34F) has been classified as Likely benign.

Submissions by phenotype
Inborn genetic diseases Uncertain:1
The c.100G>A (p.V34I) alteration is located in exon 1 (coding exon 1) of the KIAA0586 gene. This alteration results from a G to A substitution at nucleotide position 100, causing the valine (V) at amino acid position 34 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Joubert syndrome 23;C4225286:Short-rib thoracic dysplasia 14 with polydactyly Uncertain:1
This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 46 of the KIAA0586 protein (p.Val46Ile). This variant is present in population databases (rs186659284, gnomAD 0.004%). 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: 1059992). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The isoleucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
