RCV002515583 | SCV003439961 | uncertain significance | not provided | 2022-12-02 | criteria provided, single submitter | clinical testing | Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. 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. This variant disrupts the Arg162 amino acid residue in IKZF1. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 26981933). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Experimental studies have shown that this missense change affects IKZF1 function (PMID: 26981933). ClinVar contains an entry for this variant (Variation ID: 224778). This missense change has been observed in individual(s) with clinical features of IKZF1-related conditions (PMID: 26981933). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 162 of the IKZF1 protein (p.Arg162Leu). |
