Labcorp Genetics (formerly Invitae), Labcorp RCV001864390 SCV002128808 uncertain significance Alstrom syndrome 2023-11-20 criteria provided, single submitter clinical testing This sequence change replaces arginine with histidine at codon 2896 of the ALMS1 protein (p.Arg2896His). The arginine residue is weakly conserved and there is a small physicochemical difference between arginine and histidine. This variant is present in population databases (rs755542969, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with ALMS1-related conditions. ClinVar contains an entry for this variant (Variation ID: 1370861). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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.
GeneDx RCV002265038 SCV002547223 uncertain significance not provided 2022-01-10 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Ambry Genetics RCV002370413 SCV002684111 likely benign Cardiovascular phenotype 2022-06-02 criteria provided, single submitter clinical testing This alteration is classified as likely 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.
