Primary ciliary dyskinesia

Pathogenic:3

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 06, 2024	This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 248 of the CCDC114 protein (p.Ala248Thr). RNA analysis indicates that this missense change induces altered splicing and may result in an absent or disrupted protein product. This variant is present in population databases (rs147718607, gnomAD 0.05%). This missense change has been observed in individual(s) with primary ciliary dyskinesia (PMID: 23261302, 23261303). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 39637). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Studies have shown that this missense change results in the use of a cryptic splice donor site and introduces a premature termination codon (PMID: 23261302). The resulting mRNA is expected to undergo nonsense-mediated decay. For these reasons, this variant has been classified as Pathogenic. -

Pathogenic, criteria provided, single submitter	clinical testing	Ambry Genetics	Dec 20, 2017	The c.742G>A pathogenic mutation (also known as p.A248T), located in coding exon 6 of the CCDC114 gene, results from a G to A substitution at nucleotide position 742. The amino acid change results in alanine to threonine at codon 248, an amino acid with similar properties. However, this change occurs in the last base pair of coding exon 6, which makes it likely to have some effect on normal mRNA splicing. This mutation was identified in muliple individuals with primary ciliary dyskinesia in both the homozygous and compound heterozygous state (Knowles MR et al. Am. J. Hum. Genet., 2013 Jan;92:99-106; Onoufriadis A et al. Am. J. Hum. Genet., 2013 Jan;92:88-98; Boaretto F et al. J Mol Diagn, 2016 Nov;18:912-922). In addition, analysis of RNA from affected individuals homozygous for this alteration showed an insertion of 79 nucleotides, resulting in premature protein truncation (Knowles MR et al. Am. J. Hum. Genet., 2013 Jan;92:99-106; Onoufriadis A et al. Am. J. Hum. Genet., 2013 Jan;92:88-98). Based on the supporting evidence, this alteration is interpreted as a disease-causing mutation. -

The ODAD1 c.742G>A variant is predicted to result in the amino acid substitution p.Ala248Thr. This variant has been reported to segregate in multiple families with primary ciliary dyskinesia and laterality defects in the Dutch Volendam population, and is believed to be a founder mutation (Onoufriadis et al. 2013. PubMed ID: 23261303; Knowles et al. 2013. PubMed ID: 23261302). The c.742G base is the terminal nucleotide of exon 7 and alterations of this base have been shown to disrupt the adjacent GT donor site, resulting in a frameshift and premature protein termination (Onoufriadis et al. 2013. PubMed ID: 23261303; Knowles et al. 2013. PubMed ID: 23261302). This variant is reported in 0.047% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant is interpreted as pathogenic. -
