Description

This variant is a gross deletion of the genomic region encompassing exons 1-5 of the IDS gene, which includes the initiator codon. The 5' end of this event is unknown as it extends beyond the assayed region for this gene and therefore may encompass additional genes. The 3' boundary is likely confined to intron 5 of the IDS gene. This is expected to result in an absent or disrupted protein product. This variant has not been reported in the literature in individuals with IDS-related disease. Loss-of-function variants in IDS are known to be pathogenic (PMID: 8940265, 9875019). For these reasons, this variant has been classified as Pathogenic.
