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]

Bardet-Biedl syndrome 3;C3150808:Retinitis pigmentosa 55 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpSep 27, 2022This sequence change replaces arginine, which is basic and polar, with lysine, which is basic and polar, at codon 6 of the ARL6 protein (p.Arg6Lys). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The lysine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. ClinVar contains an entry for this variant (Variation ID: 1003434). This variant has not been reported in the literature in individuals affected with ARL6-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). -
