Genes affected

NPRL2 (HGNC:24969): (NPR2 like, GATOR1 complex subunit) Enables protein kinase activity. Contributes to GTPase activator activity. Involved in cellular response to amino acid starvation; negative regulation of TOR signaling; and negative regulation of kinase activity. Located in lysosomal membrane. Part of GATOR1 complex. Implicated in focal epilepsy. [provided by Alliance of Genome Resources, Apr 2022]
