Ambry Genetics

Apr 19, 2024

The c.740G>T (p.C247F) alteration is located in exon 8 (coding exon 8) of the TM6SF2 gene. This alteration results from a G to T substitution at nucleotide position 740, causing the cysteine (C) at amino acid position 247 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
