Genes affected

MPG (HGNC:7211): (N-methylpurine DNA glycosylase) Predicted to enable alkylbase DNA N-glycosylase activity. Predicted to be involved in base-excision repair. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

MPG links:

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]

The c.793G>A (p.G265S) alteration is located in exon 5 (coding exon 4) of the MPG gene. This alteration results from a G to A substitution at nucleotide position 793, causing the glycine (G) at amino acid position 265 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
