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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 20, 2023The c.1082A>G (p.N361S) alteration is located in exon 8 (coding exon 6) of the RNMT gene. This alteration results from a A to G substitution at nucleotide position 1082, causing the asparagine (N) at amino acid position 361 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
