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]

For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 2040). This premature translational stop signal has been observed in individual(s) with Bardet-Biedl syndrome (PMID: 15258860, 31456290). It has also been observed to segregate with disease in related individuals. This variant is present in population databases (rs104893678, gnomAD 0.01%). This sequence change creates a premature translational stop signal (p.Arg122*) 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). -
