Diagnostics Services (NGS), CSIR - Centre For Cellular And Molecular Biology RCV003316894 SCV004015298 likely pathogenic Griscelli syndrome type 2 2023-07-24 criteria provided, single submitter clinical testing The c.509_510del variant is not present in publicly available population databases like 1000 Genomes, EVS, Indian Exome Database or our in-house exome database. The variant is present in ExAC and genomAD, at low frequencies. The variant has neither been published in the literature for RAB27A-related conditions nor reported to clinical databases like ClinVar, Human Genome Mutation Database (HGMD) or OMIM, in any affected individuals. In-silico pathogenicity programs like MutationTaster2, CADD, Varsome, Franklin etc predicted this variant to be likely deleterious. This variant causes frameshift at the 170th amino acid position of the wild-type transcript which creates a premature translational stop signal in the altered transcript that may either result in translation of a truncated protein or cause nonsense-mediated decay of the mRNA.
