The NM_001278293.3(ARL6):c.123+165C>T variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a cumulative frequency of 0.782 (AC=118,921) in the gnomAD database across 152,014 control chromosomes, including 46,597 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.83. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign/Likely Benign (★).

Genes affected

ARL6 (HGNC:13210): (ARF 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]
