Invitae | RCV001042256 | SCV001205930 | uncertain significance | Primary ciliary dyskinesia | 2022-09-26 | criteria provided, single submitter | clinical testing | This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 3510 of the DNAH8 protein (p.Asn3510Ser). This variant is present in population databases (rs145843224, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with DNAH8-related conditions. ClinVar contains an entry for this variant (Variation ID: 840301). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt DNAH8 protein function. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. 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. |

RCV002298853 | SCV002587876 | uncertain significance | not provided | 2022-04-15 | criteria provided, single submitter | clinical testing | In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge |
Ambry Genetics | RCV002551511 | SCV003720900 | uncertain significance | Inborn genetic diseases | 2022-01-19 | criteria provided, single submitter | clinical testing | The c.10529A>G (p.N3510S) alteration is located in exon 71 (coding exon 70) of the DNAH8 gene. This alteration results from a A to G substitution at nucleotide position 10529, causing the asparagine (N) at amino acid position 3510 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |

RCV003906154 | SCV004720251 | uncertain significance | DNAH8-related condition | 2024-01-17 | criteria provided, single submitter | clinical testing | The DNAH8 c.10529A>G variant is predicted to result in the amino acid substitution p.Asn3510Ser. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.12% of alleles in individuals of African descent in gnomAD. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
