RASopathy Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Oct 17, 2023 | This variant, c.291_293del, results in the deletion of 1 amino acid(s) of the MAP2K2 protein (p.Ile97del), but otherwise preserves the integrity of the reading frame. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MAP2K2-related conditions. ClinVar contains an entry for this variant (Variation ID: 543989). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. - |
