Variant summary
Our verdict is Likely pathogenic. The variant received 8 ACMG points: 8P and 0B. PM2PM5PP3_Strong
The NM_003672.4(CDC14A):c.935G>C(p.Arg312Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000682 in 1,613,018 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. R312G) has been classified as Likely pathogenic.

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. This variant disrupts the p.Arg312 amino acid residue in CDC14A. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 29293958). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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. This variant has not been reported in the literature in individuals affected with CDC14A-related conditions. This variant is present in population databases (rs369245990, gnomAD 0.002%). This sequence change replaces arginine, which is basic and polar, with proline, which is neutral and non-polar, at codon 312 of the CDC14A protein (p.Arg312Pro). -
