Primary ciliary dyskinesia Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Feb 19, 2020 | This sequence change replaces isoleucine with valine at codon 4082 of the DNAH8 protein (p.Ile4082Val). The isoleucine residue is highly conserved and there is a small physicochemical difference between isoleucine and valine. This variant is present in population databases (rs760843520, ExAC 0.01%). 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with DNAH8-related conditions. ClinVar contains an entry for this variant (Variation ID: 407290). - |
