Functional studies provide strong evidence of the variant having a damaging effect on the gene or gene product (PMID: 23143442, 22940089, 12677556, 12118255, PS3_S). In silico tool predictions suggest damaging effect of the variant on gene or gene product (REVEL: 0.662, PP3_P). It is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: 0.001570, PM2_M). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -

Pathogenic, criteria provided, single submitterclinical testingMolecular Genetics, Royal Melbourne HospitalApr 22, 2022This sequence change is predicted to replace Methionine with Arginine at codon 390 of the BBS1 protein, p.(Met390Arg). There is a moderate physicochemical difference between Methionine and Arginine. The variant is not present in a known functional domain, and the Methionine residue is moderately conserved due to gaps in the alignment for approximately two-thirds of vertebrates assessed (100 vertebrates, UCSC). It is present in a large population cohort at a frequency of 0.2% (rs113624356, 444/282,790 alleles in gnomAD v2.1). This missense accounts for ~80% of BBS1 disease-associated alleles and ~30% of all Bardet-Biedl syndrome (BBS). It has been identified homozygous or compound heterozygous with a second pathogenic variant in BBS1 in a large number of clinically diagnosed BBS cases (PMID: 12118255, 12524598), and segregates with disease in multiple families (PMID: 12677556, 12837689). The phenotype of variant carriers varies from non-syndromic retinitis pigmentosa, mild forms of BBS, to classical BBS (PMID: 22940089, 23143442). A knock-in mouse model homozygous for p.Met390Arg has cilia defects, and recapitulates aspects of the human BBS phenotype, including retinal degeneration, male infertility, and obesity (PMID: 18032602), and partial rescue (hypomorph) was demonstrated in a zebrafish assay (PMID: 20498079). Multiple lines of computational evidence predict a deleterious effect for the missense substitution (6/6 algorithms). Based on the classification scheme RMH ACMG Guidelines v1.1.1, this variant is classified as PATHOGENIC. Following criteria are met: PM3_VeryStrong, PS3, PP1_Strong, PP3. -

Pathogenic, no assertion criteria providedclinical testingSydney Genome Diagnostics, Children's Hospital WestmeadOct 25, 2018This patient is homozygous for the c.1169T>G (p.Met390Arg) variant in BBS1 gene. The p.Met390Arg is reported in dbSNP (rs113624356) with a minor allele frequency of 0.27%. p.Met390Arg has been reported to be the most frequent cause of Bardet-Biedl syndrome (Mykytyn et al.Nature Genet 2002;31:435-438). -
Pathogenic, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpAug 04, 2016Variant summary: The BBS1 c.1169T>G (p.Met390Arg) variant involves the alteration of a conserved nucleotide. 3/4 in silico tools predict a damaging outcome for this variant (SNPs&GO not captured due to low reliability index). Met390 is conserved across vertebrates and is located in the Quinoprotein alcohol dehydrogenase-like superfamily domain. An in vivo BBS mouse model shows that mice homozygous for the M390R mutation recapitulate aspects of the human phenotype, including retinal degeneration, male infertility, and obesity (Davis_PNAS_2007).This variant is the most common BBS-causing mutation, explaining nearly 80% of all BBS patients (Davis_PNAS_2007), and was found in 182/121966 control chromosomes. The variant is commonly found in homozygous state in BBS patients, but has also been reported in compound heterozygous patients. It has been suggested that variants in other BBS genes (i.e. BBS2, BBS6, etc) may act as a severity modifier.In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as pathogenic. Taken together, this variant is a commonly known disease variant and has been classified as pathogenic. -

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpJan 31, 2024This sequence change replaces methionine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 390 of the BBS1 protein (p.Met390Arg). This variant is present in population databases (rs113624356, gnomAD 0.3%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with Bardet-Biedl syndrome and accounts for approximately 80% of BBS1 variants. It has also been observed in individual(s) with non-syndromic retinitis pigmentosa (PMID: 12118255, 12524598, 12677556, 12837689, 15314642, 22581970, 22940089, 23143442, 27032803). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 12143). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt BBS1 protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects BBS1 function (PMID: 15314642, 18032602, 20498079). For these reasons, this variant has been classified as Pathogenic. -

Pathogenic, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJun 17, 2016The p.Met390Arg variant in BBS1 has been identified in >50 individuals with Bard et-Biedl syndrome both in the homozygous and compound heterozygous states and it is the most common pathogenic variant in BBS1 (Mykytyn 2002; Mykytyn 2003, Beal es 2003, Badano 2003, Fan 2004, Cox 2012). This variant has also been identified in 0.27% (347/126644) of chromosomes by the Genome Aggregation Database (gnomAD , http://gnomad.broadinstitute.org; dbSNP rs113624356). Although this variant ha s been seen in the general population, its frequency is low enough to be consist ent with a recessive carrier frequency for Bardet-Biedl syndrome. This variant h as been reported by other clinical laboratories in ClinVar (Variation ID: 12143) . Animal models in mice have shown that this variant causes Bardet-Biedl syndrom e (Davis 2007). In summary, this variant meets our criteria to be classified as pathogenic for Bardet-Biedl syndrome in an autosomal recessive manner. ACMG/AMP Criteria applied: PS3; PM3_VeryStrong; PP3 -

This alteration results from a T to G substitution at nucleotide position 1169, causing the methionine (M) at amino acid position 390 to be replaced by an arginine (R). The p.M390R alteration is the most common pathogenic alteration in BBS1 and has been identified in numerous homozygous and compound heterozygous individuals with Bardet-Biedl syndrome (BBS) (Mykytyn, 2002; Estrada-Cuzcano, 2012; Charkoudian, 2013) as well as in compound heterozygous individuals with retinal dystrophies (Bravo-Gil, 2016). Functional studies in zebrafish lacking BBS1 and co-injected with wildtype mRNA and this mutation demonstrated only a partial rescue, consistent with a possible hypomorphic effect of this variant (Zaghloul, 2010). In addition, homozygous knock-in mice with this mutation demonstrated a phenotype similar to human BBS (Davis, 2007). Based on the available evidence, this alteration is classified as pathogenic. -

BBS1-related disorder Pathogenic:1
Pathogenic, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesSep 13, 2024The BBS1 c.1169T>G variant is predicted to result in the amino acid substitution p.Met390Arg. This missense variant is one of the most common pathogenic variants identified in patients with Bardet-Biedl syndrome (Mykytyn et al. 2002. PubMed ID: 12118255). This variant is reported in 0.28% of alleles in individuals of European (non-Finnish) descent in gnomAD and has been reported as a founder variant in individuals of European ancestry (Estrada-Cuzcano et al. 2012. PubMed ID: 23143442). In vivo and in vitro studies suggest that this variant impacts protein function (Davis et al. 2007. PubMed ID: 18032602; Zaghloul et al. 2010. PubMed ID: 20498079). This variant has been reported in the compound heterozygous and homozygous state in individuals with Bardet-Biedl syndrome (Internal Data, PreventionGenetics). This variant is interpreted as pathogenic. -
