Invitae | RCV000535358 | SCV000645335 | pathogenic | Hereditary spastic paraplegia 4 | 2017-06-29 | criteria provided, single submitter | clinical testing | This variant is a gross deletion of the genomic region encompassing exons 1-7 of the SPAST 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 7 of the SPAST gene. This is expected to result in an absent or disrupted protein product. This variant has been reported in an individual affected with hereditary spastic paraplegia. It was also found in an unaffected relative, potentially representing a case of incomplete penetrance (PMID: 17035675). Loss-of-function variants in SPAST are known to be pathogenic (PMID: 20932283). For these reasons, this variant has been classified as Pathogenic. |
