RCV002046423 | SCV002317419 | uncertain significance | Hermansky-Pudlak syndrome 2 | 2022-07-25 | criteria provided, single submitter | clinical testing | 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 proline amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 1521916). This sequence change replaces serine, which is neutral and polar, with proline, which is neutral and non-polar, at codon 12 of the AP3B1 protein (p.Ser12Pro). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with AP3B1-related conditions. 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. |
