Variant summary
Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BS2
The NM_001378030.1(CCDC78):c.863G>A(p.Arg288His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000925 in 1,610,126 control chromosomes in the GnomAD database, including 1 homozygotes. 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. R288C) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Jan 12, 2024 | This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 288 of the CCDC78 protein (p.Arg288His). This variant is present in population databases (rs200154277, gnomAD 0.06%), and has an allele count higher than expected for a pathogenic variant. This variant has not been reported in the literature in individuals affected with CCDC78-related conditions. ClinVar contains an entry for this variant (Variation ID: 473268). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on CCDC78 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. - |
