Apr 06, 2023

Labcorp Genetics (formerly Invitae), Labcorp

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the CCDC103 protein in which other variant(s) (p.Ser190Argfs*19) have been determined to be pathogenic (Invitae). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. This premature translational stop signal has been observed in individual(s) with primary ciliary dyskinesia (Invitae). This variant is present in population databases (rs746242380, gnomAD 0.007%). This sequence change creates a premature translational stop signal (p.Glu189Alafs*18) in the CCDC103 gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 54 amino acid(s) of the CCDC103 protein. -
