RCV002282832 | SCV002570634 | pathogenic | Sandhoff disease | 2022-07-19 | criteria provided, single submitter | clinical testing | Variant summary: The variant identified by MLPA or other technology involves the deletion of exons 1-5 in the HEXB gene, which includes the initiation codon. A presumed nomenclature of c.(?_-118)_(669+1_670-1)del has been designated for the purposes of this classification. The variant allele was found at a frequency of 9.2e-05 in 21694 control chromosomes (gnomAD, Structural Variants dataset). Deletion of exons 1-5 has been reported in the literature in multiple individuals affected with Sandhoff Disease (e.g. Sobek_2013, Grunseich_2015, Zanetti_2020). These data indicate that the variant is very likely to be associated with disease. Two ClinVar submitters (evaluation after 2014) cite the variant as pathogenic/likely pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic. |
