Labcorp Genetics (formerly Invitae), Labcorp RCV003116809 SCV003793020 pathogenic Hereditary spastic paraplegia 4 2022-12-15 criteria provided, single submitter clinical testing Algorithms developed to predict the effect of variants on protein structure and function are not available or were not evaluated for this variant. For these reasons, this variant has been classified as Pathogenic. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on SPAST function (PMID: 25065914). A similar copy number variant has been observed in individuals with clinical features of hereditary spastic paraplegia (PMID: 25065914; Invitae). It has also been observed to segregate with disease in related individuals. This variant results in a copy number gain of the genomic region encompassing exon(s) 9 of the SPAST gene. While the exact position of this variant cannot be determined from the data, sub-genic copy number gains are generally in tandem (PMID: 25640679). This variant is predicted to be in-frame, and likely preserves the integrity of the reading frame.
