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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 03, 2023The c.422G>T (p.C141F) alteration is located in exon 3 (coding exon 3) of the NRM gene. This alteration results from a G to T substitution at nucleotide position 422, causing the cysteine (C) at amino acid position 141 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
