GeneDx RCV000195477 SCV000252336 pathogenic not provided 2014-06-27 criteria provided, single submitter clinical testing c.2189delA: p.Asn730ThrfsX8 (N730TfsX8) in exon 17 of the SPG7 gene (NM_003119.2). The normal sequence with the base that is deleted in braces is: GCAA{A}CGCC. The c.2189delA mutation in the SPG7 gene causes a frameshift starting with codon Asparagine 730, changes this amino acid to a Threonine residue and creates a premature Stop codon at position 8 of the new reading frame, denoted p.Asn730ThrfsX8. This mutation is predicted to cause loss of normal protein function through protein truncation. Although this mutation has not been previously reported to our knowledge, another mutation downstream of c.2189delA that results in protein truncation has been reported in association with spastic paraplegia according to an external database. Therefore, we interpret c.2189delA to be a pathogenic mutation. The variant is found in MITONUC-MITOP panel(s).
