This sequence change replaces arginine with tryptophan at codon 384 of the STK11 protein (p.Arg384Trp). The arginine residue is weakly conserved and there is a moderate physicochemical difference between arginine and tryptophan. This variant is present in population databases (rs752015385, ExAC 0.004%). This variant has not been reported in the literature in individuals with STK11-related disease. ClinVar contains an entry for this variant (Variation ID: 234419). 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 tryptophan 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 and their clinical significance is uncertain. 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.
