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]

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces glycine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 169 of the ARL6 protein (p.Gly169Ala). This variant is present in population databases (rs104893679, gnomAD 0.0009%). This missense change has been observed in individual(s) with Bardet-Biedl syndrome (PMID: 15314642). It has also been observed to segregate with disease in related individuals. This variant is also known as 859G>C G169A. ClinVar contains an entry for this variant (Variation ID: 2041). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects ARL6 function (PMID: 19236846). For these reasons, this variant has been classified as Pathogenic. -
