Invitae | RCV000524982 | SCV000660320 | uncertain significance | Spermatogenic failure 18; Ciliary dyskinesia, primary, 37 | 2022-07-05 | criteria provided, single submitter | clinical testing | 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The lysine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 478519). This variant has not been reported in the literature in individuals affected with DNAH1-related conditions. This variant is present in population databases (rs369765657, gnomAD 0.009%). This sequence change replaces threonine, which is neutral and polar, with lysine, which is basic and polar, at codon 3305 of the DNAH1 protein (p.Thr3305Lys). |
Ambry Genetics | RCV003278921 | SCV003954714 | uncertain significance | Inborn genetic diseases | 2023-05-17 | criteria provided, single submitter | clinical testing | The c.9914C>A (p.T3305K) alteration is located in exon 63 (coding exon 62) of the DNAH1 gene. This alteration results from a C to A substitution at nucleotide position 9914, causing the threonine (T) at amino acid position 3305 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
