Labcorp Genetics (formerly Invitae), Labcorp RCV001385074 SCV001584785 pathogenic Holocarboxylase synthetase deficiency 2023-06-29 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 203773). This variant has not been reported in the literature in individuals affected with HLCS-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Gln75*) 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).
