Primary ciliary dyskinesia 33 Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Dec 16, 2021 | This sequence change affects the initiator methionine of the GAS8 mRNA. The next in-frame methionine is located at codon 26. This variant is not present in population databases (gnomAD no frequency). 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. Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. This variant has not been reported in the literature in individuals affected with GAS8-related conditions. - |
