Labcorp Genetics (formerly Invitae), Labcorp RCV000704289 SCV000833232 uncertain significance Hermansky-Pudlak syndrome 2 2021-08-24 criteria provided, single submitter clinical testing This sequence change replaces glycine with serine at codon 927 of the AP3B1 protein (p.Gly927Ser). The glycine residue is moderately conserved and there is a small physicochemical difference between glycine and serine. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the ExAC database. This variant has not been reported in the literature in individuals affected with AP3B1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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.
Ambry Genetics RCV002533707 SCV003731089 uncertain significance Inborn genetic diseases 2022-06-16 criteria provided, single submitter clinical testing The c.2779G>A (p.G927S) alteration is located in exon 23 (coding exon 23) of the AP3B1 gene. This alteration results from a G to A substitution at nucleotide position 2779, causing the glycine (G) at amino acid position 927 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
