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]

LRRC37A2 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -7 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.53).
