Neuroblastoma, susceptibility to, 3 Uncertain:1
This sequence change replaces arginine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 121 of the ALK protein (p.Arg121Leu). 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. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant  is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 404368). This variant has not been reported in the literature in individuals affected with ALK-related conditions. This variant is present in population databases (rs779147984, gnomAD 0.1%). -
