Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.R110Q variant (also known as c.329G>A), located in coding exon 3 of the CCDC103 gene, results from a G to A substitution at nucleotide position 329. The arginine at codon 110 is replaced by glutamine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces arginine with glutamine at codon 110 of the CCDC103 protein (p.Arg110Gln). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and glutamine. This variant is present in population databases (rs755213252, ExAC 0.08%). This variant has not been reported in the literature in individuals affected with CCDC103-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. 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. -
