GeneDx RCV000413135 SCV000491838 uncertain significance not specified 2016-11-21 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the ALMS1 gene. The T3297A variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The T3297A 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. This substitution occurs at a position that is conserved in mammals. However, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. In addition, the Exome Aggregation Consortium (ExAC) reports T3297A was observed in 91/9,788 (0.9%) alleles from individuals of African background, including one homozygous individual, indicating it may be a rare benign variant in this population. Lastly, while some missense variants have been reported in association with Alstrom syndrome, most pathogenic variants in ALMS1 reported to date are predicted to cause premature protein truncation (Marshall et al., 2012; Stenson et al., 2014).Therefore, based on the currently available information, it is unclear whether this variant is pathogenic or benign.
