Genes affected
ARL6 (HGNC:13210): (ADP ribosylation factor like GTPase 6) The protein encoded by this gene belongs to the ARF-like (ADP ribosylation factor-like) sub-family of the ARF family of GTP-binding proteins which are involved in regulation of intracellular traffic. Mutations in this gene are associated with Bardet-Biedl syndrome (BBS). A vision-specific transcript, encoding long isoform BBS3L, has been described (PMID: 20333246). [provided by RefSeq, Apr 2016]

Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Aug 06, 2023 | This variant is not present in population databases (gnomAD no frequency). For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with ARL6-related conditions. This sequence change creates a premature translational stop signal (p.Cys22*) in the ARL6 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ARL6 are known to be pathogenic (PMID: 15258860, 19858128, 20142850, 22334370, 27486776, 31736247). - |
