Genes affected

ACTL10 (HGNC:16127): (actin like 10) Predicted to be part of dynactin complex. [provided by Alliance of Genome Resources, Apr 2022]

NECAB3 (HGNC:15851): (N-terminal EF-hand calcium binding protein 3) The protein encoded by this gene interacts with the amino-terminal domain of the neuron-specific X11-like protein (X11L), inhibits the association of X11L with amyloid precursor protein through a non-competitive mechanism, and abolishes the suppression of beta-amyloid production by X11L. This protein, together with X11L, may play an important role in the regulatory system of amyloid precursor protein metabolism and beta-amyloid generation. The protein is phosphorylated by NIMA-related expressed kinase 2, and localizes to the Golgi apparatus. Multiple transcript variants encoding different isoforms have been found for this gene.
