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.5969A>G (p.Y1990C) alteration is located in exon 31 (coding exon 31) of the SPG11 gene. This alteration results from a A to G substitution at nucleotide position 5969, causing the tyrosine (Y) at amino acid position 1990 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
