Genes affected

RNMT (HGNC:10075): (RNA guanine-7 methyltransferase) Enables RNA binding activity and mRNA (guanine-N7-)-methyltransferase activity. Involved in 7-methylguanosine mRNA capping. Located in fibrillar center and nucleoplasm. Part of mRNA cap binding activity complex; mRNA cap methyltransferase complex; and receptor complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.92A>C (p.N31T) alteration is located in exon 3 (coding exon 1) of the RNMT gene. This alteration results from a A to C substitution at nucleotide position 92, causing the asparagine (N) at amino acid position 31 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
