Genes affected

NPRL3 (HGNC:14124): (NPR3 like, GATOR1 complex subunit) Contributes to GTPase activator activity. Involved in cellular response to amino acid starvation and negative regulation of TOR signaling. Located in lysosomal membrane. Part of GATOR1 complex. Implicated in focal epilepsy. [provided by Alliance of Genome Resources, Apr 2022]
