Labcorp Genetics (formerly Invitae), Labcorp RCV002932840 SCV003261617 uncertain significance Hermansky-Pudlak syndrome 2 2021-12-13 criteria provided, single submitter clinical testing This sequence change replaces serine, which is neutral and polar, with threonine, which is neutral and polar, at codon 3 of the AP3B1 protein (p.Ser3Thr). This variant is present in population databases (no rsID available, gnomAD 0.006%). 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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 RCV002932841 SCV003528577 uncertain significance Inborn genetic diseases 2024-05-07 criteria provided, single submitter clinical testing The c.8G>C (p.S3T) alteration is located in exon 1 (coding exon 1) of the AP3B1 gene. This alteration results from a G to C substitution at nucleotide position 8, causing the serine (S) at amino acid position 3 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
