Invitae | RCV001032349 | SCV001195656 | pathogenic | Charcot-Marie-Tooth disease axonal type 2F | 2019-11-04 | criteria provided, single submitter | clinical testing | This variant is a gross deletion of the genomic region encompassing exons 2-3 of the HSPB1 gene. The 5' boundary is likely confined to intron 1. The 3' end of this event is unknown as it extends through the termination codon beyond the assayed region for this gene and may encompass additional genes. While this deletion is not anticipated to result in nonsense mediated decay, it is expected to create a truncated protein product or disrupt mRNA translation. This variant has not been reported in individuals affected with HSPB1-related disorders. This variant disrupts the region of the HSPB1 protein between p.Pro39 and p.Pro182. This region has been determined to be associated with autosomal dominant HSPB1-related conditions (PMID: 27816334, 28144995, 29381233), which suggests that variants that disrupt this region are likely to be clinically significant. For these reasons, this variant has been classified as Pathogenic. |
