Labcorp Genetics (formerly Invitae), Labcorp RCV003600550 SCV004376132 pathogenic Holocarboxylase synthetase deficiency 2023-02-01 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This sequence change creates a premature translational stop signal (p.Tyr595Ilefs*10) in the HLCS gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in HLCS are known to be pathogenic (PMID: 16134170). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with HLCS-related conditions.
