Genes affected

NSF (HGNC:8016): (N-ethylmaleimide sensitive factor, vesicle fusing ATPase) Enables PDZ domain binding activity and ionotropic glutamate receptor binding activity. Involved in intracellular protein transport; positive regulation of protein catabolic process; and positive regulation of receptor recycling. Located in Golgi apparatus; cytosol; and plasma membrane. Implicated in developmental and epileptic encephalopathy. [provided by Alliance of Genome Resources, Apr 2022]

Jun 11, 2024

The c.1615G>A (p.V539M) alteration is located in exon 14 (coding exon 14) of the NSF gene. This alteration results from a G to A substitution at nucleotide position 1615, causing the valine (V) at amino acid position 539 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
