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]

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 12 ACMG points.

PVS1
Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.009819968 fraction of the gene. Cryptic splice site detected, with MaxEntScore 6.9, offset of 4, new splice context is: tagGTaaag. Cryptic site results in frameshift change. If cryptic site found is not functional and variant results in exon loss, it results in inframe change.
PM2
Very rare variant in population databases, with high coverage;
PP5
Variant 15-44622727-C-T is Pathogenic according to our data. Variant chr15-44622727-C-T is described in ClinVar as Pathogenic. ClinVar VariationId is 41288.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
