RCV001233411 | SCV001406004 | uncertain significance | Hermansky-Pudlak syndrome 2 | 2022-10-05 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 515 of the AP3B1 protein (p.Pro515Arg). 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. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 959971). This variant has not been reported in the literature in individuals affected with AP3B1-related conditions. This variant is not present in population databases (gnomAD no frequency). |
