Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.185T>G (p.F62C) alteration is located in exon 3 (coding exon 1) of the RNMT gene. This alteration results from a T to G substitution at nucleotide position 185, causing the phenylalanine (F) at amino acid position 62 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
