Genes affected

ALMS1 (HGNC:428): (ALMS1 centrosome and basal body associated protein) This gene encodes a protein containing a large tandem-repeat domain as well as additional low complexity regions. The encoded protein functions in microtubule organization, particularly in the formation and maintanance of cilia. Mutations in this gene cause Alstrom syndrome. There is a pseudogene for this gene located adjacent in the same region of chromosome 2. Alternative splice variants have been described but their full length nature has not been determined.

Variant summary: ALMS1 c.10235A>G (p.Glu3412Gly) results in a non-conservative amino acid change in the encoded protein sequence. Three of four in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00052 in 249224 control chromosomes, predominantly at a frequency of 0.0065 within the East Asian subpopulation in the gnomAD database, including 1 homozygote. The observed variant frequency within East Asian control individuals in the gnomAD database is approximately 4.5 fold of the estimated maximal expected allele frequency for a pathogenic variant in ALMS1 causing Alstrom Syndrome phenotype (0.0014). To our knowledge, no occurrence of c.10235A>G in individuals affected with Alstrom Syndrome and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 373524). Based on the evidence outlined above, the variant was classified as likely benign. -

Significance:Uncertain significance

Review Status:flagged submission

Collection Method:clinical testing

One individual with Leber congenital amaurosis (LCA) has been reported to be homozygous for the E3414G variant (published using alternative nomenclature E3412G) in the ALMS1 gene, though neither deletion analysis of the ALMS1 gene nor parental consanguinity status or genotypes were reported (Wang et al., 2015). Furthermore, this individual was also apparently homozygous for a truncating variant in the LCA5 gene, which would better explain a typical LCA phenotype. The E3414G variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. Though E3414G variant was not observed with any significant frequency in over 80,000 individuals of European and African ancestry in the Exome Aggregation Consortium, it was reported in 42/8554 (0.5%) alleles in individuals of East Asian background. Additionally, this substitution occurs at a position that is not conserved across species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Lastly, while some missense variants have been reported in association with Alstrom syndrome, most pathogenic variants in ALMS1 reported to date introduce a premature termination codon (Marshall et al., 2012; Stenson et al., 2014). -

Significance:Benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
