The ALK c.1550A>G (p.His517Arg) missense change has a maximum subpopulation frequency of 0.04% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org/variant/2-29541267-T-C?dataset=gnomad_r2_1). Six of six in silico tools predict a benign effect of this variant on protein function (BP4), but to our knowledge these predictions have not been confirmed by functional assays. To our knowledge, this variant has not been reported in the literature in individuals with ALK-related neuroblastic tumor susceptibility. In summary, this variant meets criteria to be classified as of uncertain significance based on the ACMG/AMP criteria: BP4.
