Genes affected
DNAH8 (HGNC:2952): (dynein axonemal heavy chain 8) The protein encoded by this gene is a heavy chain of an axonemal dynein involved in sperm and respiratory cilia motility. Axonemal dyneins generate force through hydrolysis of ATP and binding to microtubules. [provided by RefSeq, Jan 2012]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 13, 2023 | The c.11182C>G (p.P3728A) alteration is located in exon 75 (coding exon 74) of the DNAH8 gene. This alteration results from a C to G substitution at nucleotide position 11182, causing the proline (P) at amino acid position 3728 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
Primary ciliary dyskinesia Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Sep 01, 2021 | This sequence change replaces proline with alanine at codon 3728 of the DNAH8 protein (p.Pro3728Ala). The proline residue is highly conserved and there is a small physicochemical difference between proline and alanine. This variant is present in population databases (rs138016358, ExAC 0.01%). This variant has not been reported in the literature in individuals affected with DNAH8-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Not Available"; Align-GVGD: "Class C0"). 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. - |
