RCV001004869 | SCV001164349 | uncertain significance | Allan-Herndon-Dudley syndrome | 2018-12-03 | criteria provided, single submitter | research | The hemizygous p.Ala150Thr variant in SLC16A2 was identified by our study in two siblings with Allan-Herndon-Dudley syndrome. The p.Ala150Thr variant in SLC16A2 has not been previously reported in individuals with Allan-Herndon-Dudley syndrome but has been identified in 0.001249% (1/80047) of European (non-Finnish) chromosomes, in 1 hemizygote, by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs373279555), suggesting that this variant is not pathogenic for Allan-Herndon-Dudley syndrome. Computational prediction tools and conservation analyses suggest that this variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. Two additional variants at the the same position, p.Ala150Val and p.Ala150Glu, have been reported pathogenic and likely pathogenic in association with disease in ClinVar, supporting that a change at this position may not be tolerated (Variation ID: 11634, 159907). In summary, the clinical significance of the p.Ala150Thr variant is uncertain. ACMG/AMP Criteria applied: BS2, PM5, BP4 (Richards 2015). |
