Primary ciliary dyskinesia Pathogenic:1Uncertain:1
Uncertain significance, no assertion criteria provided | clinical testing | Natera, Inc. | Feb 21, 2020 | - - |
Pathogenic, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 19, 2025 | This sequence change falls in intron 16 of the DNAH5 gene. It does not directly change the encoded amino acid sequence of the DNAH5 protein. It affects a nucleotide within the consensus splice site. This variant is present in population databases (rs369244905, gnomAD 0.1%). This variant has been observed in individual(s) with clinical features of DNAH5-related conditions (internal data). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 351201). Variants that disrupt the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. - |
Primary ciliary dyskinesia 3 Pathogenic:1Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Jan 13, 2018 | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. - |

not provided Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Apr 28, 2017 | The c.2431+5G>A variant in the DNAH5 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant reduces the quality of the splice acceptor site in intron 16, and is expected to cause abnormal gene splicing. The c.2431+5G>A variant is observed in 11/10390 (0.11%) alleles from individuals of African background, in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). We interpret c.2431+5G>A as a variant of uncertain significance. - |
DNAH5-related disorder Uncertain:1
Uncertain significance, no assertion criteria provided | clinical testing | PreventionGenetics, part of Exact Sciences | Jun 07, 2024 | The DNAH5 c.2431+5G>A variant is predicted to interfere with splicing. Based on available splicing prediction software, this variant is predicted to impact the exon 16 consensus splice donor site and affect splicing (SpliceAI, Jaganathan et al. 2019. PubMed ID: 30661751). However, prediction programs are imperfect and we cannot be certain of the biological impact of this particular variant. This variant has been reported in an individual undergoing testing for primary ciliary dyskinesia (PCD); although, clinical details of the patient and information on an additional DNAH5 variant were not provided (Table 1, De Jesús-Rojas et al. 2022. PubMed ID: 35626283). This variant is reported in 0.11% of alleles in individuals of African descent in gnomAD. At PreventionGenetics, this variant has been reported, along with an additional DNAH5 variant, in unrelated individuals undergoing PCD testing (Internal Data). Although we suspect that this variant may be pathogenic, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. - |
