Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 22, 2022The c.964T>C (p.F322L) alteration is located in exon 7 (coding exon 5) of the RNMT gene. This alteration results from a T to C substitution at nucleotide position 964, causing the phenylalanine (F) at amino acid position 322 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
