Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 0P and 0B.
The NM_145038.5(DRC1):c.617G>A(p.Arg206Gln) variant causes a missense change. The variant allele was found at a frequency of 0.000116 in 1,614,106 control chromosomes in the GnomAD database, with no homozygous occurrence. 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. R206W) has been classified as Uncertain significance.

Inborn genetic diseases Uncertain:1
The c.617G>A (p.R206Q) alteration is located in exon 5 (coding exon 5) of the DRC1 gene. This alteration results from a G to A substitution at nucleotide position 617, causing the arginine (R) at amino acid position 206 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
Primary ciliary dyskinesia Uncertain:1
This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 206 of the DRC1 protein (p.Arg206Gln). This variant is present in population databases (rs141540461, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with DRC1-related conditions. ClinVar contains an entry for this variant (Variation ID: 565442). 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 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. -
