This sequence change replaces lysine, which is basic and polar, with glutamine, which is neutral and polar, at codon 978 of the WDR11 protein (p.Lys978Gln). This variant is present in population databases (rs144531702, gnomAD 0.03%). This missense change has been observed in individual(s) with WDR11-related conditions (PMID: 20887964). ClinVar contains an entry for this variant (Variation ID: 68841). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. -

Variant summary: WDR11 c.2932A>C (p.Lys978Gln) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. Consensus agreement among computation tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.00018 in 249696 control chromosomes. This frequency is not significantly higher than estimated for a pathogenic variant in WDR11 causing WDR11-Related Disorders, allowing no conclusion about variant significance. c.2932A>C has been reported in the literature in three heterozygous individuals affected with WDR11-Related Disorders; however, this variant has also been detected in two control subjects (Kim_2010, Federici_2022). These report(s) do not provide unequivocal conclusions about association of the variant with WDR11-Related Disorders. One experimental study has shown that this variant does not affect splicing in an in vitro exon trapping assay (Kim_2010). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 36531499, 20887964). ClinVar contains an entry for this variant (Variation ID: 68841). Based on the evidence outlined above, the variant was classified as uncertain significance. -
