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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 14, 2021The c.884G>A (p.R295Q) alteration is located in exon 9 (coding exon 9) of the NPRL2 gene. This alteration results from a G to A substitution at nucleotide position 884, causing the arginine (R) at amino acid position 295 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
