Genes affected

SPG11 (HGNC:11226): (SPG11 vesicle trafficking associated, spatacsin) The protein encoded by this gene is a potential transmembrane protein that is phosphorylated upon DNA damage. Defects in this gene are a cause of spastic paraplegia type 11 (SPG11). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2009]

The c.7249G>A (p.E2417K) alteration is located in exon 40 (coding exon 40) of the SPG11 gene. This alteration results from a G to A substitution at nucleotide position 7249, causing the glutamic acid (E) at amino acid position 2417 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
