Labcorp Genetics (formerly Invitae), Labcorp RCV000798980 SCV000938625 uncertain significance Hermansky-Pudlak syndrome 9 2018-08-24 criteria provided, single submitter clinical testing This sequence change replaces glutamine with glutamic acid at codon 69 of the BLOC1S6 protein (p.Gln69Glu). The glutamine residue is moderately conserved and there is a small physicochemical difference between glutamine and glutamic acid. This variant is present in population databases (rs775671194, ExAC 0.03%). This variant has not been reported in the literature in individuals with BLOC1S6-related disease. 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 tolerated, but 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.
