Genes affected
SNAP91 (HGNC:14986): (synaptosome associated protein 91) Predicted to enable several functions, including SNARE binding activity; clathrin binding activity; and phosphatidylinositol binding activity. Acts upstream of or within regulation of clathrin-dependent endocytosis. Predicted to be located in several cellular components, including postsynaptic density; presynaptic endosome; and presynaptic membrane. Predicted to be extrinsic component of endosome membrane. Predicted to be active in several cellular components, including Schaffer collateral - CA1 synapse; cytoplasmic vesicle; and parallel fiber to Purkinje cell synapse. Predicted to be extrinsic component of presynaptic endocytic zone membrane. Biomarker of Alzheimer's disease. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2022The c.2314G>C (p.G772R) alteration is located in exon 25 (coding exon 24) of the SNAP91 gene. This alteration results from a G to C substitution at nucleotide position 2314, causing the glycine (G) at amino acid position 772 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
