Primary ciliary dyskinesia Uncertain:2
Nov 01, 2017
Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.387_388insCGT variant (also known as p.F129_D130insR), located in coding exon 4 of the CCDC114 gene, results from an in-frame CGT insertion at nucleotide positions 387 to 388. This results in the insertion of an extra arginine residue between codons 129 and 130. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Labcorp Genetics (formerly Invitae), Labcorp
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This variant, c.387_388insCGT, results in the insertion of 1 amino acid(s) of the CCDC114 protein (p.Phe129_Asp130insArg), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs779459076, gnomAD 0.06%). This variant has been observed in individual(s) with primary ciliary dyskinesia (PMID: 32111882). This variant is also known as rs779459076, C/CACG ‚àí/R. ClinVar contains an entry for this variant (Variation ID: 406183). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. -

ODAD1-related disorder Uncertain:1
Dec 19, 2023
PreventionGenetics, part of Exact Sciences
Significance:Uncertain significance
Review Status:no assertion criteria provided
Collection Method:clinical testing

The ODAD1 c.387_388insCGT variant is predicted to result in an in-frame amino acid insertion (p.Phe129_Asp130insArg). This variant has been reported in the homozygous state in an individual with primary ciliary dyskinesia (patient SI13, Postema MC et al 2020. PubMed ID: 32111882). This variant is reported in 0.063% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
