This sequence change replaces serine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 13 of the INTU protein (p.Ser13Ala). This variant is present in population databases (rs143620669, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with INTU-related conditions. An algorithm developed to predict the effect of missense changes on protein structure and function outputs the following: PolyPhen-2: "Benign". The alanine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
