Uncertain significance, criteria provided, single submitter | clinical testing | Genomic Research Center, Shahid Beheshti University of Medical Sciences | Mar 05, 2018 | - - |
not provided Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Mar 08, 2022 | 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 ARMC9-related conditions. This variant is not present in population databases (gnomAD no frequency). This variant, c.1770_1772del, results in the deletion of 1 amino acid(s) of the ARMC9 protein (p.Asp590del), but otherwise preserves the integrity of the reading frame. - |
