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]

Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.6944A>C (p.N2315T) alteration is located in exon 38 (coding exon 38) of the SPG11 gene. This alteration results from a A to C substitution at nucleotide position 6944, causing the asparagine (N) at amino acid position 2315 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
