ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.13017306).
BS1
Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.0000595 (87/1461830) while in subpopulation EAS AF = 0.000882 (35/39700). AF 95% confidence interval is 0.000651. There are 0 homozygotes in GnomAdExome4. There are 44 alleles in the male GnomAdExome4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Primary ciliary dyskinesia Uncertain:1
Aug 27, 2021
Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This sequence change replaces asparagine with serine at codon 302 of the CCDC114 protein (p.Asn302Ser). The asparagine residue is moderately conserved and there is a small physicochemical difference between asparagine and serine. This variant is present in population databases (rs145222993, ExAC 0.04%). This missense change has been observed in individual(s) with primary ciliary dyskinesia (PMID: 23261302). 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 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. -
