Diagnostics Lab (ASPIRE), CSIR - Centre for Cellular and Molecular Biology RCV000856816 SCV000999188 pathogenic Hermansky-Pudlak syndrome 1 2019-08-05 criteria provided, single submitter clinical testing The c.1657C>T is a nonsense variant, creating a premature stop codon at 553 position, that may result a truncated protein or nonsense mediated decay (NMD) and c.507+2T>G is a donor splice-site variant, may affect the splicing.This variant is not present only in publicly available databases like 1000 Genomes, Exome Variant Server (EVS), Exome Aggregation Consortium (ExAC), Genome Aggregation Database (gnomAD) and dbSNP. The variant is not present in our in-house exome database. This variant was not reported earlier in other patients of HPS1 in OMIM, HGMD and ClinVar databases. In-silico pathogenicity prediction programs like SIFT, Polyphen2, Mutation Taster2, CADD, InterVar etc. predicted it to be likely disease causing. As per ACMG guidelines the variant has been classified as pathogenic.
