There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: (SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). The methionine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies. This variant is present in population databases (rs754971913, ExAC 0.006%) but has not been reported in the literature in individuals with an ALK-related disease. This sequence change replaces valine with methionine at codon 569 of the ALK protein (p.Val569Met). The valine residue is highly conserved and there is a small physicochemical difference between valine and methionine. |
