Genes affected

NRM (HGNC:8003): (nurim) The protein encoded by this gene contains transmembrane domains and resides within the inner nuclear membrane, where it is tightly associated with the nucleus. This protein shares homology with isoprenylcysteine carboxymethyltransferase enzymes. Alternative splicing results in multiple transcript variants that encode different protein isoforms.

Collection Method: clinical testing

The c.106G>A (p.G36R) alteration is located in exon 1 (coding exon 1) of the NRM gene. This alteration results from a G to A substitution at nucleotide position 106, causing the glycine (G) at amino acid position 36 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
