Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1PM2PP3_StrongPP5_Moderate
The NM_001278293.3(ARL6):āc.506G>Cā(p.Gly169Ala) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000118 in 1,613,646 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Pathogenic (ā ). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G169C) has been classified as Uncertain significance.

Bardet-Biedl syndrome 3;C3150808:Retinitis pigmentosa 55 Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Oct 06, 2023 | 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. - |
