Ambry Genetics

Nov 22, 2021

The c.19C>T (p.L7F) alteration is located in exon 1 (coding exon 1) of the TRMT11 gene. This alteration results from a C to T substitution at nucleotide position 19, causing the leucine (L) at amino acid position 7 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
