GeneDx RCV001008528 SCV001168300 pathogenic not provided 2019-02-06 criteria provided, single submitter clinical testing A pathogenic variant has been identified in the SPAST gene. The c.1454_1463del10 variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The c.1454_1463del10 variant causes a frameshift starting with codon Alanine 485, changes this amino acid to a Glycine residue and creates a premature Stop codon at position 42 of the new reading frame, denoted p.Ala485GlyfsX42. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The c.1454_1463del10 variant is not observed in large population cohorts (Lek et al., 2016). Therefore, this variant is considered to be a pathogenic variant, and its presence is consistent with spastic paraplegia type 4.
