Ambry Genetics

Nov 24, 2024

The c.1222T>C (p.F408L) alteration is located in exon 10 (coding exon 10) of the TM7SF3 gene. This alteration results from a T to C substitution at nucleotide position 1222, causing the phenylalanine (F) at amino acid position 408 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
