Genes affected

CLSTN1 (HGNC:17447): (calsyntenin 1) This gene is a member of the calsyntenin family, a subset of the cadherin superfamily. The encoded transmembrane protein, also known as alcadein-alpha, is thought to bind to kinesin-1 motors to mediate the axonal anterograde transport of certain types of vesicle. Amyloid precursor protein (APP) is trafficked via these vesicles and so this protein is being investigated to see how it might contribute to the mechanisms underlying Alzheimer's disease. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2014]

The c.2906A>G (p.Q969R) alteration is located in exon 19 (coding exon 19) of the CLSTN1 gene. This alteration results from a A to G substitution at nucleotide position 2906, causing the glutamine (Q) at amino acid position 969 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
